From: Dynamic changes in genetic diversity, drug resistance mutations, and treatment outcomes of falciparum malaria from the low-transmission to the pre-elimination phase on the islands of São Tomé and Príncipe

  1. Factors correlated with the levels of parasite density (log10 transformed) are characterized using linear regression model. The definition of each variable is described in the method section. Parasite density in the low transmission periods (Period B and C, 2010–2013) are compared with that in the pre-elimination phase (Period D, 2014–2016) using dummy variables. Significant p-values (p < 0.05) are shown in italic
