1 · What the graph read from it

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.

2 · The registry

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

aimThe aim of this study was to evaluate the safety, tolerability, and pharmacokinetics of single escalating oral doses of DDCI-01 (a novel, highly selective, long-acting phosphodiesterase type 5 inhibitor) administered via capsules to healthy volunteers.

methodsThis randomized, double-blind, placebo-controlled, single ascending dosing, Phase Ia clinical study involved 52 healthy volunteers who were randomized (3:1 ratio) to receive a single oral dose of DDCI-01 (1.25, 2.5, 5, 10, 20, 40, or 60 mg) or a placebo. Adverse events and pharmacokinetic parameters were evaluated after 14 days post-administration.

resultsWithin the studied dose range, DDCI-01 was safe and tolerable. Mild adverse events incidence was > 10% in all 39 volunteers receiving DDCI-01: myalgia (eight cases, 20.51%) and spontaneous penile erection (four cases, 10.26%). Drug exposure (C

conclusionsDDCI-01 demonstrated favorable safety and pharmacokinetic profiles within the dose range. The findings of this first-in-human study support further research for the indications of DDCI-01, such as pulmonary arterial hypertension and erectile dysfunction.
