Fig. 3From: Molecular epidemiology of human papillomavirus among HIV infected women in developing countries: systematic review and meta-analysisForest plot to estimate the pooled prevalence of high risk human papillomavirus infection among HIV infected women (the estimate weighted based on random effects model): ES—effect Size equivalent to prevalence, CI—confidence interval. In the plot, the diamond shows the pooled result and the boxes show the effect estimates from the single studies. The purple dotted vertical line indicates pooled estimate. The purple solid vertical line indicates the reference line at zero indicating no effect. The horizontal line through the boxes illustrate the length of the confidence interval and the boxes show the effect estimates from the single studiesBack to article page
