Propensity scores (PS) are typically evaluated using balance metrics that focus on covariate balance, often without considering their predictive power for the outcome. This approach may not always res...
We conduct a series of simulations alongside an analysis of empirical observational data to compare the performances of weighted treatment effect estimates using the proposed and existing approaches. ...
The simulation and empirical data analysis reveal that our proposed model-averaging approaches for PS estimation consistently yield lower bias and less variability in treatment effect estimates across...
The prognostic score-based model averaging approach for estimating PS can outperform existing model averaging methods. In particular, the estimator using the model averaging prognostic score as a bala...
Using the prognostic score as the balance metric for the PS model averaging enhances the performance of the treatment effect estimator, which can be recommended for a wide variety of situations. When ...
There has been growing interest in using nonparametric machine learning approaches for propensity score estimation in order to foster robustness against misspecification of the propensity score model....
Propensity score weighting is a useful tool to make causal or unconfounded comparisons between groups. According to the definition by the Institute of Medicine (IOM), estimates of health care disparit...
The present study introduces a deweighting method that uses two types of propensity scores. One is a function of all covariates of health status and SES variables and is used to weight study subjects ...
The procedure of deweighting is illustrated using a dataset from a right heart catheterization (RHC) study, where it was used to examine whether there was a disparity between black and white patients ...
Deweighting is a promising tool for implementing the IOM-definition of health care disparities. The method is expected to be broadly applied to quantitative research on health care disparities....
Liver resection (LR) is the only recommended effective curative treatment for patients with intrahepatic cholangiocarcinoma (ICC), but the prognosis of patients with ICC is still poor even after curat...
Reports of redo laparoscopic colorectal resection (Re-LCRR) are scarce. In order to evaluate the safety and short-term outcomes of Re-LCRR, we performed a matched case-control analysis of patients who...
This was a retrospective, monocentric study that included patients who underwent Re-LCRR for colorectal cancer between January 2011 and December 2019 at our institution. The patients were compared to ...
Twenty-nine patients underwent Re-LCRR (RCRR group) and were compared to 58 patients selected by matching who underwent LCRR as primary resection (PCRR group). The median of age of the 29 patients of ...
Re-LCRR is associated with good short-term results and can be safely performed; however, the number of harvested lymph nodes is significantly reduced in comparison to primary resection cases, and furt...
Colostomy is a common procedure for fecal diversion, but the optimal colostomy approach is unclear in terms of surgical outcomes and stoma-related complications. The purpose of this study was to exami...
This retrospective cohort study included patients who underwent loop colostomy at Shizuoka Cancer Center in Japan between April 2010 and March 2022. Patients were divided into two groups based on surg...
Of the 388 eligible patients, 180 (46%) were in the LAP group and 208 (54%) were in the OPEN group. The male-to-female ratio was 5.5:4.5 in the Lap group and was 5.3:4.7 in the OPEN group, respectivel...
Our results suggest that laparoscopic surgery could be beneficial and feasible in loop colostomy....
Propensity score weighting is a popular approach for estimating treatment effects using observational data. Different sets of propensity score-based weights have been proposed, including inverse proba...
We considered 648 scenarios defined by different values of the prevalence of treatment, the c-statistic of the propensity score model, the correlation between the linear predictors for treatment selec...
We found that, when the prevalence of treatment was low or high and the c-statistic of the propensity score model was moderate to high, that matching weights, overlap weights, and entropy weights had ...
Researchers using matching weights, overlap weights, and entropy weights should not assume that the estimated treatment effect is comparable to the ATE....
Spontaneous rupture is a fatal complication of hepatocellular carcinoma (HCC). This study compared the prognosis of spontaneously ruptured HCC (srHCC) with that of non-ruptured HCC (nrHCC)....
A total of 185 srHCC patients and 1085 nrHCC patients treated by hepatectomy between February 2005 and December 2017 at Zhongshan Hospital were retrospectively reviewed and enrolled. The overall survi...
Before PSM, patients with srHCC who underwent hepatectomy (n = 185) had a poorer prognosis than those with nrHCC (n = 1085; 5-year OS, 39.1% vs 59.2%, P < 0.001; 5-year TTR, 83.8% vs 54.9%, P < 0.001)...
Spontaneous rupture of HCC is not a risk factor for survival. If resected eventually, srHCC may achieve comparable survival with nrHCC....
Infection is a serious complication of primary total ankle arthroplasty (TAA) and can lead to implant failure and revision surgery. Various demographic, comorbidity, and surgical factors have been ass...
A retrospective cohort study was conducted using data from a single institution from 2002 to 2022. Patients who underwent primary TAA and had subsequent infection were identified through annual regist...
A total of 1863 patients who underwent primary TAA were identified, and 19 were diagnosed with an infection. The identifiable overall infection rate was 1.0%. After PSM, there were no significant diff...
This study demonstrated high rates of a history of smoking and diabetes in the infected TAA cohort. The diabetes rate in the infected group was significantly higher than the noninfected controls. Two-...
Level III, case-control study....
Minimal invasiveness improves outcome in many surgical fields including urology. We aimed to assess intraoperative performance and clinical outcome of miniaturized holmium laser enucleation of prostat...
We ran a propensity score-matched analysis among all consecutive laser enucleations of prostate performed between 9/2022 and 2/2023. It resulted in two matched comparison groups: MiLEP 22 FR (n = 40) ...
MiLEP was associated with significantly less intraoperative irrigation (20.5 L vs 15 L, p = 0.002...
MiLEP is feasible and provides better maintenance of body core temperature, reduction in amount of fluid irrigation, and decrease in need for meatal dilation without affecting effectiveness in compari...
