Variance of dataset dominated by infection status. PCA model (A) and PLS-DA model (B) score plots of ¹H NMR spectra across all time-points from both studies. Plasmodium falciparum parasite cultures (PF) in red (n = 112), uninfected erythrocyte cultures (RBC) in blue (n = 40) and fresh media samples are coloured green (n = 48). Cumulative values of model fit (R²) and model prediction (Q²) for the first two components are denoted on both plots.
