“…The quality assessment did not reveal major methodological pitfalls among the included studies. The most common shortcoming was the absence of detailed description of statistical models [ 34 , 37 , 38 , 40 , 44 , 47 , 48 , 49 , 50 , 56 , 58 , 59 , 60 , 62 , 66 , 69 , 71 , 77 , 80 , 84 , 85 , 86 , 88 , 90 , 91 , 93 , 104 ], though without impacting the overall quality. Moreover, some studies did not provide results about demographics, albeit information considering the estimation of our primary outcome was integral ( Supplementary Table S3 ) [ 17 , 36 , 77 , 84 , 93 , 94 , 99 , 100 ].…”
