Figure 5.
Comparison of HTA reviews with other reviews using PRISMA. In nine PRISMA items the HTA reviews were significantly better reported than in other types of reviews. The numbered items (#) correspond to the PRISMA item numbers (see table 1). In item #5, the relative risk was undefined, but, Fisher's exact test demonstrated a significant difference, (p = 0.0038), in favour of the HTA reports. RR (95% CI) denotes the relative risk with the associated 95% confidence interval.
