Figure 3

Higher-risk sex practice in prior 12 months by wealth index (2003–2009). M-H = Mantel-Haenszel statistic; CI = confidence interval. Note: we divided the wealth index into two categories, namely, lowest or low (i.e., the first or second quintile) and middle to highest (i.e., the third through fifth quintiles), to make it fit for the meta-analysis software.
