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

backgroundAlthough proxies of patients with chronic obstructive pulmonary disease (COPD) need health-related knowledge to support patients in managing their disease, their current level of knowledge remains unknown. We aimed to compare health-related knowledge (generic and COPD-related knowledge) between patients with COPD and their resident proxies.

methodsIn this cross-sectional study, we included stable patients with moderate to very severe COPD and their resident proxies (n = 194 couples). Thirty-four statements about generic health and COPD-related topics were assessed in patients and proxies separately. Statements could be answered by 'true', 'false', or 'do not know'. This study is approved by the Medical Research Ethics Committees United (MEC-U), the Netherlands (NL42721.060.12/M12-1280).

resultsPatients answered on average 17% of the statements incorrect, and 19% with 'do not know'. The same figure (19%) for the incorrect and unknown statements was shown by proxies. Patients who attended pulmonary rehabilitation previously answered more statements correct (about three) compared to patients who did not attend pulmonary rehabilitation. More correct answers were reported by: younger patients, patients with a higher level of education, patients who previously participated in pulmonary rehabilitation, patients with better cognitive functioning, and patients with a COPD diagnosis longer ago.

conclusionsProxies of patients with COPD as well as patients themselves answer about two third of 34 knowledge statements about COPD correct. So, both patients and proxies seem to have an incomplete knowledge about COPD and general health. Therefore, education about general health and COPD should be offered to all subgroups of patients with COPD and their proxies.

trial registrationThis study is registered in the Dutch Trial Register ( NTR3941 ). Registered 19 April 2013.
