Fig. 3From: Changing epidemiology of Plasmodium vivax malaria in Nouakchott, Mauritania: a six-year (2015–2020) prospective studyTrend of malaria prevalence and rainfall pattern in Nouakchott from 2015 to 2020. The annual rainfall and the annual prevalence of PCR-confirmed malaria showed a linear relationship (probability of departure from linearity, P = 0.900) and a statistically significant correlation (Pearson correlation coefficient r = 0.853; goodness of fit, r2 = 0.727; two-tailed P = 0.031; \(y=2.235x+47.511\))Back to article page
