The mean differences and significance between baseline and 8 week follow-up scores are shown in Table 2. CLBP: Chronic low back pain.
Table 1 presents the mean differences and significance level between LS and SS groups for each questionnaire (HAD components anxiety 1 and depression 2, SF-36 components physical 3 and mental 4, TSC-33).
When trials all use the same PRO it is important to report results beyond a mean difference and statistical significance.
When trials all use the same PRO it is important to report results beyond a mean difference and statistical significance as suggested above.
In a two one-sided test analysis for additive equivalence of paired means with bounds -5 and +5 for the mean difference and a significance level of 0.05, assuming a mean difference of 0, a common standard deviation of 16 and correlation 0.9, a sample size of 19 pairs, was required to obtain a power of at least 0.8.
In a two-sided tests analysis for additive equivalence of paired means for a given KOOS with bounds -5 and 5 for the mean difference and a significance level of 0.05, assuming a mean difference of 0 KOOS points, a common Standard Deviation of 20, and correlation 0.95, a sample size of 20 pairs yielded a power of 0.922 (> 90%).
In a two one-sided tests (TOST) analysis for additive equivalence of two-sample normal means with bounds -12 and 12 for the mean difference and a significance level of 0.05, assuming a null difference and a common standard deviation of 25%, a sample size of 76 patients with arm lymphedema per group is required to obtain a power of at least 0.8.

All of the improvement in BE is explained by change in SID from mean value of 31.0 to 34.2 mmol/L (mean difference 3.2 mmol/L, correlation significance of p < 0.001).
