Forest plots of cohort-specific and meta-analysis results for the interactions of (A) IGF-1 and dichotomized CRP on MRI measures and (B) IGFBP-3 and dichotomized CRP on MRI measures. CRP was dichotomized according to the 75th percentile (<75th percentile, ≥75th percentile).
Beta estimates and 95% confidence intervals (CI) are presented graphically in the center, where the square represents beta coefficients and the error bars the 95% confidence intervals per cohort according to the text on the right column. Meta-analysis results derived from random-effects (RE) models are presented with diamonds.
Models are adjusted for age, age-squared, sex, time between blood draw and MRI, waist-to-hip ratio, systolic blood pressure, hypertension treatment, diabetes mellitus, current smoking, and prevalent cardiovascular disease.
