Risk factors associated with the incidence of wild poliovirus type 1 (WPV1) cases based on the best-fitting multivariable mixed-effects lagged regression model for January–June 2010 through July–December 2016.

The odds ratio (OR) and the 95% confidence interval (CI) for routine immunization and supplementary immunization activity (SIA) coverage are for an absolute 10% increase in these variables and a 1-unit increase for all other variables. Non-polio acute flaccid paralysis (AFP) rate is per 100,000 persons aged

针对常规免疫与补充免疫活动（supplementary immunization activity, SIA）的覆盖率，其比值比（odds ratio, OR）及95%置信区间（confidence interval, CI）的计算基准为：上述两类免疫的覆盖率绝对增长10%，其余变量每单位增长。非脊髓灰质炎急性弛缓性麻痹（non-polio acute flaccid paralysis, AFP）的发病率统计单位为每10万名年龄段人群。
