TL;DR: This analysis demonstrates a 20% increase in the risk of childhood-onset type 1 diabetes after Caesarean section delivery that cannot be explained by known confounders.

TL;DR: The pooled analysis suggests weak protective associations between exclusive breast-feeding and type 1 diabetes risk, however, these findings are difficult to interpret because of the marked variation in effect and possible biases (particularly recall bias) inherent in the included studies.

TL;DR: Children who are heavier at birth have a significant and consistent, but relatively small increase in risk of type 1 diabetes.

TL;DR: There was evidence of a weak but significant linear increase in the risk of childhood type 1 diabetes across the range of maternal ages, but the magnitude of association varied between studies.

TL;DR: There was some evidence of a lower risk of childhood onset type 1 diabetes with increasing birth order, particularly in children aged < 5 years, which could reflect increased exposure to infections in early life in later born children.
