Seventeen studies reported prevalence of ความผิดปกติด้านการอยากอาหาร (appetite disorder) in AD ranging from 11% to 64%. Overall, there were 6,424 AD patients with a pooled prevalence of 34% (95% CI 27–41%) และ a significant ความไม่เหมือนกัน (heterogeneity) (I2 = 97.1%, P < 0.05) between estimates (Supplementary Fig. 12). The subsequent meta-regression analyses revealed that the factor of study setting (p = 0.022) และ duration (p = 0.011) might be interpretation for some of the variance in the estimates across studies (Table 1).
