“…Meta-analysis of three studies (Ou, 2005; Niu, 2009; Lai, 2013) showed that CHMs paratherapy were significant for decreasing MG clinical absolute and relative score ( n = 156, MD −2.36, 95% CI: −3.10 to −1.61, p < 0.00001; heterogeneity χ 2 = 1.53, df = 2, p = 0.47, I 2 = 0%, Figure 4 ) compared to pyridostigmine bromide and corticosteroids; one (Ju, 2003) study also have positive result compared with corticosteroids ( p < 0.01); three studies (Barohn et al, 1998; Bao, 2016; Bao et al, 2016) failed to pool analysis because of high heterogeneity and all showed statistical significant difference compared with pyridostigmine bromide ( p < 0.01). Meta-analysis of four studies (Ou, 2005; Niu, 2009; Lai, 2013; Shuang and Tan, 2014) showed CHMs paratherapy significantly improved the total clinical effective rate ( n = 194, RR 1.05, 95% CI: 0.99–1.12, p = 0.11; heterogeneity χ 2 = 0.79, df = 3, p = 0.85, I 2 = 0%, Figure 5 ) compared with pyridostigmine bromide and corticosteroids; two studies (Ju, 2003; Zu, 2015) are similar result ( n = 90, RR 1.06, 95% CI: 0.94–1.20, p = 0.34; heterogeneity χ 2 = 0.16, df = 1, p = 0.69, I 2 = 0%) compared with corticosteroids; five studies (Wang et al, 2008; Liang, 2011; Jiang et al, 2014; Bao, 2016; Bao et al, 2016) failed to pool analysis because of high heterogeneity and all showed statistical significant difference compared with pyridostigmine bromide ( p < 0.01). Meta-analysis of five studies (Ju, 2003; Xu et al, 2004; Wang et al, 2008; Liang, 2011; Lai, 2013) showed that CHMs paratherapy were significant for improving the relapse rate after follow-up ( n = 291, OR 0.22, 95% CI: 0.11–0.48, p = 0.0001; heterogeneity χ 2 = 0.77, df = 4, p = 0.94, I 2 = 0%, Figure 6 ) compared WCM controls.…”
