Fig. 2From: The sit-to-stand test as a patient-centered functional outcome for critical care research: a pooled analysis of five international rehabilitation studiesDistribution of scores, including individual assessments (left) and difference scores for paired assessments (right). We considered a floor as ≥ 15% of patients with minimum score and ceiling as ≥ 15% of patients with the maximum score. For 30 s STS, we considered the “maximum” score to be the upper limit of the 95% confidence interval for sex-matched normative values (29 repetitions for women, 32 for men) (Tveter et al., 2014). For patients with assessments completed at ICU and hospital discharge, difference scores were calculated by subtracting scores at ICU discharge from hospital discharge. d/c, Discharge; ax, assessment; and STS, sit to standBack to article page
