Trends of the incidence rate, mortality rate, and case fatality ratio by age groups in Niger. Joinpoint regression models were used to estimate the annual percentage change (APC) of malaria from 2010 to 2019 stratified by age groups. Blue points indicate the observed rate of malaria and the curve indicates fitted patterns by blue points. *APC is significantly different from zero at two-sided P < 0.05
