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 hypertension (PH) is a common complication of chronic obstructive pulmonary disease (COPD) without effective drugs to treat. We conducted a systematic review and meta-analysis in order to evaluate whether PH specific therapies were effective for stable COPD patients. Data were extracted from PubMed, Cochrane Central Register of Controlled Trials and China Knowledge Resource Integrated Database. Randomized controlled trials (RCTs) with PH specific therapy treated more than 4 weeks in COPD were selected. The main outcome was exercise capacity; meanwhile pulmonary arterial pressure (PAP), hypoxemia and health related life quality were also measured. We included nine trials involving 365 subjects, among which two were treated with bosentan and seven with sildenafil. The study time varied from 4 weeks to 18 months and mostly it was 12 weeks. In a pooled analysis of nine trials, exercise capacity of COPD patients was improved by PH-specific therapy [mean difference (MD) 66.39 m, 95% confidence intervals (CI): 59.44-73.34]. COPD with severe PH (mean PAP >35 mmHg by right heart catheterization or systolic PAP >50 mmHg by echocardiography) improved the exercise capacity (MD 67.24 m, 95% CI: 60.26-74.23), but COPD without PH at rest did not (MD -9.24 m, 95% CI: -75.08 to 56.31). Meanwhile PAP was decreased (MD -9.02 mmHg, 95% CI: -10.71 to -7.34 mmHg). Although hypoxemia and life quality were not improved, the dyspnea was alleviated or at least not aggravated (Borg dyspnea index, MD -0.86, 95% CI: -1.86 to 0.14). In conclusion, PH specific drugs (especially sildenafil) could improve exercise capacity and decrease PAP in COPD patients with severe PH.
