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

STUDY

objectivesTo undertake a meta-analysis of literature comparing the prevalence of cardiovascular and cerebrovascular comorbidities between patients with overlap syndrome (OS) and patients with chronic obstructive pulmonary disease (COPD) or patients with obstructive sleep apnea.

methodsStudies about the cardiovascular and cerebrovascular disease of OS were searched for among several electronic databases from the time of database construction to June 2019. Two independent reviewers performed the process of study screening, quality assessment, and data extraction. Meta-analysis of odds ratios (ORs) was carried out by RevMan5.3 under either fixed-effects or random-effects models. Sensitivity analysis was conducted to examine the robustness of pooled outcome.

resultsA total of 17 articles were included. Compared with COPD/obstructive sleep apnea, OS significantly increased the risk of developing hypertension (OS vs COPD: OR = 1.94, 95% confidence interval [CI] [1.49, 2.52]; OS vs obstructive sleep apnea: OR = 2.05, 95% CI [1.57, 2.68]) and pulmonary hypertension (OS vs COPD: OR = 2.96, 95% CI [1.30, 6.77]; OS vs obstructive sleep apnea: OR = 5.93, 95% CI [1.84, 18.42]). There was no significant difference in the prevalence of coronary heart disease (OR = 1.19, 95% CI [.67,2.11]) and cerebrovascular disease (OR = 2.43, 95% CI [0.81, 7.31]) between patients with COPD and patients with OS. However, the sensitivity analysis showed that the pooled outcome of the comparison of pulmonary arterial pressure between patients with OS and patients with COPD was not stable.

conclusionsOS significantly increased cardiovascular risk including the prevalence of hypertension and pulmonary hypertension. However, since the pooled outcome about pulmonary arterial pressure was not stable, further studies are still required.
