Figure 6From: Efficacy of praziquantel and artemisinin derivatives for the treatment and prevention of human schistosomiasis: a systematic review and meta-analysisFunnel plot and Egger's publication bias test for RCTs of PZQ's efficacy on schistosomiasis treatment. The pooled log-RR for these trials is shown with a dashed vertical line, and the dashed slash lines distributed in both sides are the cutoff values of 95% CI of pooled log RR. The Egger's publication bias test showed that no publication bias exists (P = 0.96).Back to article page
