% RCAI: % Relative Cell Aggregation Index (median)

25%–75%: 25th and 75th percentiles

Different fractions of P. vivax schizont extracts (S1 – acetone fraction, S2 – ethanol fraction, S3 – petroleum ether fraction, S4 – diethyl ether fraction and S5 – remaining fraction ) and similar fractions of paroxysm plasma ( P1 – acetone fraction, P2 – ethanol fraction, P3 – petroleum ether fraction, P4 – diethyl ether fraction and P5 – remaining fraction ) were tested for their ability to induce cell aggregation with or without supplementation with recombinant human cytokines (TNFα, GM-CSF, IL-6 and IL-10).

The table provides the median values together with the interquartile range (25%–75%).
