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

backgroundEvaluating the efficacy and safety of low molecular weight heparin (LMWH) for patients with chronic obstructive pulmonary disease (COPD) and respiratory failure (RF) is a major purpose of this study.

methodsThe following electronic databases will be comprehensively retrieved from the inception to July 1, 2019: Cochrane Library, PUBMED, EMBASE, Google Scholar, Web of Science, Allied and Complementary Medicine Database, WANGFANG, and China National Knowledge Infrastructure without language restrictions. All randomized controlled trials related to LMWH for COPD and RF will be included. Two authors will carry out study selection, data collection, and risk of bias assessment independently.

resultsThis study will systematically explore the efficacy and safety of LMWH for COPD and RF. The primary outcome is lung function. The secondary outcomes are severity of dyspnea on exertion, quality of life, body mass index, airflow obstruction; and any expected and unexpected adverse events.

conclusionThe findings of this study will provide evidence to judge whether LMWH is an effective treatment for patients with COPD and RF. PROSPERO REGISTRATION NUMBER: PROSPERO CRD42019 139631.
