The Relationship between Active Trachoma and Ocular <i>Chlamydia trachomatis</i> Infection before and after Mass Antibiotic Treatment - Fig 4

<p>A Forest plot showing the relationship between Active Trachoma (TF or TF/TI) and the detection of <i>C</i>. <i>trachomatis</i> infection at the individual level (a) before and (b) after the introduction of MDA, grouped by community TF prevalence level. Studies are ordered by increasing prevalence of TF, the size of the grey boxes represent the how much weight each study contributes to the overall estimate, the blue diamonds represent the subtotal and overall pooled odds ratio estimates. The odds ratios are for ocular <i>C</i>. <i>trachomatis</i> infection as the outcome and TF as the explanatory variable.
