Figure 2From: Increased sample volume and use of quantitative reverse-transcription PCR can improve prediction of liver-to-blood inoculum size in controlled human malaria infection studies Correlation analyses. Data were compiled from all samples in both clinical trials where two methods produced results ≥ LLQ. Paired results were plotted as shown; Spearman rank correlation (R); two-tailed p value. Units for x and y axes are log10 p/mL whole blood as determined for paired samples by the methods listed on each axis.Back to article page
