Correction to: Effect of action-based cognitive remediation on cognition and neural activity in bipolar disorder: study protocol for a randomized controlled trial.

"4 weeks of treatment (four active ABCR sessions twice a week or control group sessions twice a week)" should have actually been described as "4 weeks of treatment (4 active, twice a week, ABCR sessions or 2 weekly control group sessions)".
