Registries with missing IDs and crude incidence rates (cases/100,000 women) calculated considering only a portion of these as new cases (likely scenario).

This equals one new diagnosis every 1.67 discharges. The last row shows the variation among these crude rates and those shown in Fig 1.这等价于每1.67次出院即产生一例新增诊断病例。最后一行展示了上述粗率（crude rate）与图1中所示粗率之间的变异情况。
