Relative geometric mean concentrations* of male IGFs and IGFBPs by alcohol consumption. p for heterogeneity is the heterogeneity of means between categories, tested using the F test. p for trend was calculated using the analysis of variance test, with categorical variables entered as linear values scored as the median value within each category and excluded nondrinkers. *Relative to 1–9 g ethanol/day, adjusted for study, age, height, BMI and smoking status. #Significant heterogeneity by study p < 0.01. Abbreviations: IGF, insulin‐like growth factor; IGFBP, insulin‐like growth factor‐binding protein.
