Meta-analysis of the association between birth weight (three categories) and risk for breast cancer. The tests for homogeneity and for publication bias in the studies analyzed are as follows. Category I (birth weight 3,000 to 3,999 g) versus reference (<3,000 g): Q = 4.97 (11 degrees of freedom), P = 0.93; Begg test, P = 0.54; Egger test, P = 0.27. Category II (≥4,000 g) versus reference: Q = 13.44 (11 degrees of freedom), P = 0.27; Begg test, P = 0.54; Egger test, P = 0.53. CI, confidence interval; OR, odds ratio.
