Fig. 2: Cochrane risk of bias 2 (RoB 2).
From: The overlooked role of exergames in cognitive-motor neurorehabilitation: a systematic review

RoB 2 was used to evaluate bias across five domains: (1) bias arising from the randomization process, (2) deviations from intended interventions, (3) missing outcome data, (4) measurement of outcomes, and (5) selection of reported results. Each study will be classified as having low risk, some concerns, or high risk of bias.
