Sensitivity analysis and publication bias
Sensitivity analysis indicated that any removal of the studies from the
meta-analysis, create no change in the results of the meta-analysis on
CK and LDH concentration. Funnel plots for CK and LDH were visually
symmetrical (Figure 4) , and the Begg’s test results did not
determine any publication bias evidence in articles that examine the
effect of creatine supplementation on CK (Begg’s test, P = 0.176) and on
LDH (Begg’s test, P = 0.185).
