Figure 4: Univariate metaregression between net change in HDLC and lipid profile of preexercise. (a) Graph of metaregression between net change in HDLC and TC of preexercise. Lower preexercise TC level correlated with net change of HDLC. Each circle represents each trial and its area is proportional to the study weight. (b) Table of univariate metaregression between net change in HDLC and TC, TG, LDLC, HDLC of preexercise. *Significance P < 0.05. The calculation of net change in HDLC and TC was the same with Figure 2. Coef = Coefficient; Std Err = Standard error; 95% CI = 95% confidence interval, HDLC = Highdensity lipoprotein cholesterol, TC = Total cholesterol, TG = Triglycerides
