FIGURE 2.

Joinpoint regression analysis of stage‐specific trends in ASIRs of lung cancer by histological type. (A) Male stage‐specific ASIRs of SMC before imputation; (B) Male stage‐specific ASIRs of SMC after imputation; (C) Female stage‐specific ASIRs of SMC before imputation; (D) Female stage‐specific ASIRs of SMC after imputation; (E) Male stage‐specific ASIRs of SQC before imputation; (F) Male stage‐specific ASIRs of SQC after imputation; (G) Female stage‐specific ASIRs of SQC before imputation; (H) Female stage‐specific ASIRs of SQC after imputation; (I) Male stage‐specific ASIRs of ADC before imputation; (J) Male stage‐specific ASIRs of ADC after imputation; (K) Female stage‐specific ASIRs of ADC before imputation; (L) Female stage‐specific ASIRs of ADC after imputation. ADC, adenocarcinoma; ASIRs, age‐standardized incidence rates; SMC, small cell carcinoma; SQC, squamous cell carcinoma. The three Japanese cancer registries are in Yamagata, Fukui and Nagasaki prefectures. The colored dots are the observed rates; colored lines are the joinpoint model‐fitted rates
