Estimating reference intervals from an IPD meta-analysis using quantile regression.

Reference intervals, which define an interval in which a specific proportion of measurements from a healthy population are expected to fall, are commonly used in medical practice. Synthesizing informa... With the availability of individual participant data (IPD), non-parametric methods can be used to estimate reference intervals without any distributional assumptions. Furthermore, patient-level covari... We compared several non-parametric bootstrap methods through simulation studies to account for within-study correlation. Under fixed effects model, we recommend keeping the studies fixed and only rand... We proposed to use the quantile regression in the IPD meta-analysis to estimate the reference interval. Based on the simulation results, we identify an optimal bootstrap strategy for estimating the un...

Hospitalization costs of road traffic injuries in Hunan, China: A quantile regression analysis.

We extracted the data of all inpatients (n = 60535) with road traffic injuries during the year 2019 from Chinese National Health Statistics Network Reporting System database in Hunan, China. We calcul... The median hospitalization cost was $853.48, and the median length of hospital stay was 9 days. Vulnerable road users accounted for 84.9 % of all cases. Medicine cost is the first driver of hospitaliz... Road traffic injuries cause huge healthcare costs for victims, most of whom are vulnerable road users.

Relationship between obsessive compulsive symptomatology and severity of psychotic symptoms in schizophrenia: Meta-analysis and meta-regression analysis.

Schizophrenia patients often show obsessive-compulsive symptoms (OCS) and obsessive-compulsive disorder (OCD) and their presence has been associated with poorer prognosis. However, the impact of OCS/O... A systematic review and meta-analysis (SRMA) of studies comparing the severity of psychotic symptoms among schizophrenia patients with and without OCS/OCD was performed. Standardized mean difference (... Sixty-seven studies involving 7740 patients were included. Patients with schizophrenia and OCS/OCD showed a slightly higher severity of positive (SMD = 0.17, p value = 0.0089) and global psychotic sym... Comorbid OCS/OCD in schizophrenia has, at most, a minor impact on psychotic severity. Variability in this effect was considerable and was poorly explained by the covariates analyzed....

Endoscopic third ventriculostomy for shunt malfunction in the pediatric population: a systematic review, meta-analysis, and meta-regression analysis.
