Evaluation of the Pharmacokinetics of Trazpiroben (TAK-906), a Peripherally Selective D
Trial report in Clinical pharmacology : advances and applications, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03161405 (A Single-Sequence, Open-Label, 2-Period, Crossover Trial to Evaluate the Effect of the Potent CYP3A4 Inhibitor Itraconazole on the Single-Dose Pharmacokinetics of Oral TAK-906 in Healthy Adult Subjects), which is not on this map.

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.

Abstract
purposeTreatment options for gastroparesis, such as metoclopramide and domperidone, are limited because of safety concerns, which may be exacerbated in the presence of inhibitors of drug metabolism. This study evaluated the effect of itraconazole on the pharmacokinetics, safety, and tolerability of trazpiroben (previously TAK-906), a novel, peripherally selective D
methodsThis was a phase 1, two-period, crossover trial in healthy participants (NCT03161405). On day 1, period 1 (days 1-3), participants received a single oral dose of trazpiroben 25 mg. During period 2 (days 4-9), participants received oral itraconazole 200 mg once daily (days 1-5) and one oral dose of trazpiroben 25 mg post itraconazole on day 4. Trazpiroben pharmacokinetics were assessed. Safety assessments included triplicate electrocardiograms.
resultsTwelve healthy males (24-45 years old) were studied. Co-administration of itraconazole increased trazpiroben area under the concentration-time curve from time 0 to infinity by 1.28-fold (90% confidence interval: 1.10, 1.49) and maximum plasma concentration (C
conclusionThese results indicate that TAK‑906 is relatively insensitive to inhibition of cytochrome P450 3A4, and cardiovascular safety concerns associated with domperidone are unlikely to be elicited by trazpiroben under similar conditions.
