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

Pulmonary arterial hypertension (PAH) is a fatal disease defined as a mean pulmonary artery pressure exceeding 25 mmHg when diagnosed with right heart catheterisation. Its pathophysiology involves multiple molecular pathways, including key components leading to an inflammatory and oxidative stress environment that ultimately causes right ventricular hypertrophy and failure. Compared to the developed world, the overall PAH prevalence is higher in developing countries, including Africa, where it is mostly associated with left heart disease, obstructive/restrictive pulmonary disease, HIV and rheumatic heart disease. Current targeted PAH treatments are expensive, not always available in developing countries, and have a limited impact on PAH progression and mortality rate. Therefore, there is an urgent need for effective and affordable medications that can be used as adjunct therapy against PAH in developing countries. Recently, there have been mounting pre-clinical and clinical data suggesting that melatonin may provide health benefits against PAH.
