In this study, the inverse variance weighting method was used as the predominant analysis method and was complemented by MR-Egger and weighted median methods. Horizontal pleiotropy and potential outliers were detected by employing the MR-PRESSO method.Results: This study indicated that obesity rises the possibility of acute upper respiratory infections (BMI: OR=1.
