 ^{a}breast cancer only; N: number of studies; *N = 4; OR: odds ratio; CI: confidence interval; P_{het}: P value for heterogeneity; the metaanalysis was conducted using the fixedeffects model unless otherwise stated; ^{R}randomeffects model (Bold indicates increased risk).
 I^{2} values as measure of heterogeneity are considered low (<44%), moderate (4574%) or high (>75%).
