Fig. 5From: The use of maoto (Ma-Huang-Tang), a traditional Japanese Kampo medicine, to alleviate flu symptoms: a systematic review and meta-analysisForest plot of fever duration after drug administration: maoto vs. neuraminidase inhibitors (NAIs). The duration of fever does not differ significantly between maoto and NAIs. The heterogeneity is significant (P < 0.1, I2 > 75%), and a random-effects model is used for this outcome. The plot shows three studies by Kawamura [19, 21, 23] and one by Nabeshima et al. [25]. The full-text articles of these studies were carefully checked for duplication of participantsBack to article page
