Table 2 Statistically significance and clinically relevance on continuous outcomes of LBP. Δ is the MID. Negative values means improvement (for example, greater pain reduction in the treatment vs. control group)

From: Rehabilitation interventions in randomized controlled trials for low back pain: proof of statistical significance often is not relevant

Scenario N° of trials (%) (total = 42) N° of comparisons (%) (total = 81)

A) statistically significant and clinically relevant
15 (36%) 20 (25%)

B) statistically significant but not clinically relevant
10 (24%) 22 (27%)

C) not statistically significant but clinically relevant
1 (2%) 1 (1%)

D) not statistically significant and not clinically relevant
16 (38%) 38 (47%)
