The average duration of physical therapy per day (top panel) and the average duration of occupational therapy per day (bottom panel) is presented for the four groups of patients included in the current study, i.e. placebo treated control patients, patients treated with EPA, patients treated with HMB, and patients treated with the combination of HMB and EPA. Both figures present data for individual subjects included in the four experimental groups. Group means for the experimental groups are presented as vertical bars (top of bar) and error bars indicate the 95% CI of the mean for the experimental groups. The mean duration of physical therapy per day was 3.23 min (95% CI 1.43–5.04), 4.72 min (95% CI 2.12–7.31), 2.12 min (95% CI 0.48–3.77), and 3.27 min (95% CI 1.48–5.06), respectively, for Control, EPA, HMB, and HMB + EPA groups (p = 0.278). The mean duration of occupational therapy per day was 2.8 min (95% CI 1.4–4.2), 3.1 min (95% CI 1.5–4.7), 1.5 min (95% CI 0.2–2.5), and 3.2 min (95% CI 1.5–4.9), respectively, for Control, EPA, HMB, and HMB + EPA groups (p = 0.267)
