Concentration-Response Analysis of the Combination of Pyronaridine and Piperaquine on Corrected QT Interval From a Randomized, Double-Blind, Placebo-Controlled Study in Healthy Adults of African Sub-Saharan Origin.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A novel oral combination of the long-acting antimalarials pyronaridine (PYR) and piperaquine (PQP) has potential for malaria chemoprevention. This single-center randomized, double-blind, placebo-controlled study assessed the effects of PYR and PQP alone and when co-administered on Fridericia-corrected QT interval (QTcF). Between February 14, 2022, and May 31, 2022, thirty-seven healthy black adults of African sub-Saharan origin were enrolled and randomized to PYR + PQP (n = 15), PYR + placebo (n = 8), PQP + placebo (n = 8) or double placebo (n = 6) administered once daily (fasted) for 3 days at doses approved for malaria treatment. Triplicate digitalized electrocardiogram (ECG) recordings and pharmacokinetic samples were taken at matched timepoints. Concentration-response analysis was performed for QTcF changes from baseline (ΔQTcF), and the impact of PYR, PQP, and PYR + PQP administration on placebo-corrected ΔQTcF (ΔΔQTcF) was assessed. The final qualified and validated concentration-QTc model included a linear component for PYR and an E
