Summary of impact of screening on population prevalence of Chlamydia infections as computed by the model.

Declines are measures in percentage points (pp), i.e. the difference between two percentages. For comparison, the prevalence estimates derived from the positivity measures in the CSI program [13] are presented in Table 5.降幅以百分点（percentage points，pp）为计量单位，即两个百分比数值之间的差值。为便于对比，CSI项目[13]中基于阳性检测指标推导得到的流行率估算值已列于表5中。
