Consumption of vegetables and fruits and breast cancer survival: a systematic review and meta-analysis.

ABSTRACT: We aimed to conduct a meta-analysis investigating the association between consumption of vegetables and fruits and breast cancer survival. A comprehensive search of the PubMed and EMBASE was performed from the inception to September 30, 2016. The summary hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using a random effects model. Ten studies, with a total of 31,210 breast cancer cases, were included in the meta-analysis. The summary HRs (95% CIs) of overall survival (highest vs. lowest) were 1.08 (0.88-1.33; I² = 41.1%) for pre-diagnostic intake of vegetables and fruits combined, 0.96 (0.71-1.30; I² = 48.4%) for vegetables alone, and 0.83 (0.67-1.02; I² = 0) for fruit alone. No significant risk associations of overall survival were fo
