CHD, coronary heart disease; T2D, type 2 diabetes.
For meta-analyses that did not report dose-response estimation, the result of the highest compared with the lowest category was reported.
P < 0.00125 was considered significant to avoid inflating the rate of false-positive findings due to multiple testing.
