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

backgroundAsymmetric dimethylarginine (ADMA) has emerged as a risk marker for many conditions related to pulmonary hypertension (PH); however, little is known about ADMA and symmetric dimethylarginine (SDMA) plasma concentrations in chronic obstructive pulmonary disease (COPD). Our interest centers on the role of ADMA in regulation of endothelial function in COPD and secondary PH. The aim of the present study was to evaluate the serum ADMA, SDMA, and L-arginine concentrations in COPD and its association with PH.

methodsPatients with diagnosis of COPD underwent pulmonary function tests, echocardiography, and laboratory investigations including ADMA, SDMA, and L-arginine.

resultsSerum concentrations of ADMA, SDMA, and L-arginine tend to increase as COPD progresses. Patients with PH had higher concentrations of ADMA, SDMA, and L-arginine compared to cases with normal pulmonary arterial pressure (PAP); the difference was not statistically significant.

conclusionsOur results show that increased ADMA, SDMA, and L-arginine concentrations are associated with increased PAP measurements in patients with COPD, however, the relationship is not statistically significant.
