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

objectivePulmonary hypertension (PH) is a common complication of chronic obstructive pulmonary disease (COPD) associated with a decrease in the survival rate of patients with COPD. Our aim was to investigate whether PH impairs the functional capacity and symptoms in patients with COPD. In addition, we aimed to evaluate the correlation between the functional capacity and symptoms score in patients with COPD. MATERIALS AND

methodsThis prospective cross-sectional study enrolled 64 patients with moderate to severe COPD, prospectively. All patients underwent the pulmonary function test, echocardiography, 6-minute walk test (6MWT), and cardiopulmonary exercise testing (CPET). We applied the modified Medical Research Council (mMRC) dyspnea scale and COPD Assessment Test (CAT) to all patients. The mean pulmonary arterial pressure (mPAP) >30 mmHg with echocardiography was considered as PH. The patients were grouped according to the presence of PH as COPD-PH (n=30) and COPD-nonPH (n=34).

resultsHospitalization rate was higher in the COPD-PH group than in the COPD-nonPH group (p=0.006). The 6MWT results were lower in the COPD-PH group compared to the COPD-nonPH group (325±61 m vs. 354±46 m, respectively, p=0.025). In the COPD-PH group, the maximum oxygen consumption (VO

conclusionAn elevated PAP in patients with COPD limits the exercise capacity. Using CPET in the functional evaluation of patients with COPD may be beneficial in the early detection of PH.
