“…The comorbidities [ 34 , 45 , 60 ], preexisting hypertension [ 34 , 45 , 55 ], lung disease [ 12 , 34 , 51 , 52 , 58 ], high VAS [ 28 , 49 , 52 - 54 , 56 ], former smoking [ 12 , 34 , 48 ], current smoking [ 54 , 60 ], and depression [ 34 , 39 , 40 , 52 , 54 , 60 ] were categorized as basic health status. By the random-effects model, the results indicated that preexisting hypertension, lung disease, and depression were risk factors for post-COVID-19 fatigue, with a pooled OR of 1.24 (95% CI: 1.08-1.42; p=0.002), 2.71 (95% CI: 1.07-6.89; p=0.036), and 1.55 (95% CI: 1.01-2.39; p=0.045).…”
