Table 2 Magnitude-based inference results

From: The effects of pre versus post workout supplementation of creatine monohydrate on body composition and strength

  POST-SUPP PRE-SUPP   
Measures Mean ± SD Mean ± SD Difference ± 90CIa Qualitative Inference
BW (kg) 0.8 ± 0.9 0.4 ± 2.2 0.4 ± 1.3 Trivial
FFM (kg) 2.0 ± 1.2 0.9 ± 1.8 1.1 ± 1.2 Possibly beneficial
FM (kg) −1.2 ± 1.6 −0.1 ± 2.0 1.1 ± 1.5 Possibly beneficial
1-RM BP (kg) 7.6 ± 6.2 6.6 ± 8.2 1.2 ± 1.7 Likely beneficial
  1. Changes in body composition and performance in PRE-SUPP vs. POST-SUPP groups, and qualitative inferences about the effects on body composition and bench press strength.
  2. Values reported as mean ± standard deviation (SD); BW body weight, FFM fat-free mass, FM fat mass. a ± 90% CI: add and subtract this number to the mean difference to obtain the 90% confidence intervals for the true difference. Qualitative inference represents the likelihood that the true value will have the observed magnitude.
