Figure 4.

Violin plots showing the drug-induced Long QT Syndrome (LQTS) risk score factor at baseline and after the virtual addition of repurposed drugs into PACE participants’ drug regimens. Fexofenadine was used as a negative control and terfenadine alone and combined with AZ were used as positive controls on drug-induced LQTS score. The white dots are the medians, and the colored areas are probability density estimates. p < 0.0001 compared to the baseline for all repurposed drugs and terfenadine (alone and combined with AZ). Abbreviations: HCQ, hydroxychloroquine; AZ, azithromycin; CQ, chloroquine; and LPV/r, lopinavir + ritonavir.
