We only included studies with randomized controlled designs in the final meta-analysis.
A total of 20 effect estimates from 15 studies were included in the final meta-analysis.
The final meta-analysis included six published articles with 730 RPL cases and 613 controls.
Twenty-three studies with 1013 participants were included in the final meta-analysis.

Seven studies were included in the final meta-analysis, covering a total of 9697 T1DM cases and 8455 controls.

The final meta-analysis included four studies.
