Pharmacokinetics, safety, and tolerability of an oxfendazole tablet formulation: a phase 1, randomized, placebo-controlled trial in healthy African volunteers.

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
Oxfendazole, a registered veterinary drug, has demonstrated broad-spectrum activity against multiple nematode species. First-in-human studies in healthy, predominantly Caucasian adults receiving a liquid formulation of oxfendazole demonstrated a favorable pharmacokinetic and safety profile, supporting its potential as a drug candidate for treating human helminth infections. To further advance its clinical development, we conducted a phase I bioavailability study using a field-applicable, immediate-release oxfendazole tablet. This trial investigated the pharmacokinetics, safety, and tolerability of the tablet formulation in healthy African adults residing in a filariasis-endemic country. Oxfendazole was administered as a single dose (100 or 400 mg) or as multiple doses (400 mg for 5 consecutive days) to 30 participants, randomized 8:2 to oxfendazole or placebo per cohort. Plasma concentrations of oxfendazole were measured using a validated high-performance liquid chromatography tandem mass spectrometry method, and pharmacokinetics were assessed using non-compartmental analysis. Peak plasma concentrations were reached after ~2.5-3 h. The median elimination half-life ranged from 11.6 to 13.9 h and was consistent across cohorts. Non-linear pharmacokinetics was observed, with exposure (AUC
