  • NOTE: Complete cases, that is, women with both baseline and follow-up measurements, are presented. Therefore, baseline values may differ from the values as presented in Table 1. Complete case data of CRP was available for n = 229 (94.2%) women, 1 woman was excluded because of an abnormal CRP value at follow-up (>25 mg/L). IL6, adiponectin, leptin, n = 231 [control, n = 44 (91.7%); diet, n = 94 (96.9%); mainly exercise, n = 93 (94.9%)].

  • aTER: the treatment effect ratio (and 97.5% or 95% CI) represents the overall intervention effect on change in biomarker (adjusted for baseline biomarker level), estimated by linear regression analysis. The linear regression models were based on log-transformed biomarker data, therefore, the treatment effect is a ratio that indicates how many times the biomarker level is, on average, higher (TER>1) or lower (TER<1) in (i) the intervention group compared with the control group, or (ii) mainly exercise compared with the diet group. For example, TER = 0.9 indicates that the biomarker level in the intervention group is on average 10% lower compared with the control group.

  • bP < 0.025 is considered significant for the comparison of both intervention groups vs. control, a matching 97.5% CI is presented.

  • cP < 0.05 is considered significant for the comparison mainly exercise vs. diet, a matching 95% CI is presented.
