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

purposeLung volume reduction surgery (LVRS) has been shown to improve lung function, but also improve the overall quality of life (QOL). The aim of this study is to compare two QOL questionnaires-EuroQol Questionnaire (EQ-5D-3L) and 36-item Short Form Health Survey (SF-36) in patients post-LVRS.

methodsAll patients undergoing LVRS for severe chronic obstructive pulmonary disease (COPD) at a single center of excellence were analyzed (n = 94). Baseline demographic and clinical outcomes were characterized. Both EQ-5D-3L and SF-36 questionnaires were administered to all patients at baseline (n = 94) and at the end of 1 year (n = 89) post-surgery. SF-36 was converted to Short Form six-dimensions (SF-6D) using standard algorithm. Correlation, discrimination, responsiveness and differences across the two questionnaires were examined.

resultsThe mean age of patients enrolled in the cohort was 66 years. There was significant increase in forced expiratory volume (FEV1, 43%), forced vital capacity (FVC 46%), diffusion capacity (DLCO 15%), 6 min walk distance test (6MWD 21%) and a significant decrease in residual volume (RV 23%) at the end of 1-year follow-up. The overall mean utility index significantly improved for both SF-6D and EQ-5D-3L questionnaires at the end of follow-up (p = 0.0001). However, the magnitude of percentage increase was higher with EQ-5D-3L compared to SF-6D (32% vs. 13%). Stronger correlations confirmed convergent validity at the end of 1-year follow-up between similar domains. Both questionnaires failed to discriminate between different levels of disease severity post-LVRS in patients with severe COPD.

conclusionsBoth questionnaires responded similarly in patients with COPD post-LVRS. Combining results from QOL questionnaire(s) along with symptoms of disease and history of exacerbation may be a possible solution for identifying disease severity in old and sick patients unwilling/unable to come to hospital for a pulmonary function test post-LVRS.
