*Positive fold change indicates overexpression in severe malaria and symptoms of severity compared to UM as well as parasites showing cytoadhesion compared to none. Total number of miRNAs in RNA sequencing data was 1,450. p value adjusted for multiple testing by the Benjamini-Hochberg method. baseMean, mean normalized expression of the miRNAs in all the samples; miRNA, microRNA; SA, severe anemia, SM, severe malaria; UM, uncomplicated malaria.
