Figure 2From: Timing of progression from Chlamydia trachomatisinfection to pelvic inflammatory disease: a mathematical modelling study Predicted cumulative incidence of chlamydial PID for the three types of timing of progression. Panel A, results for intervention group; panel B, results for control group. Immediate progression (dashed line); constant progression (solid line); progression at the end (dashed-dotted line). The fraction progressing from chlamydia to PID is varied from 0-100% using baseline values for all other model parameters.Back to article page
