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

The St. George's Respiratory Questionnaire (SGRQ) and chronic obstructive pulmonary disease (COPD) assessment test (CAT) are the measures used to assess health status. This study aims to examine the responsiveness of these tools by severity of dyspnoea category in patients with COPD. Forty-nine COPD patients who underwent a 12-week pulmonary rehabilitation (PR) programme were assessed at baseline, 12 weeks and at 28-week follow-up. Patients were categorized into two groups by severity of dyspnoea category (i.e. mild to moderate (modified Medical Research Council (mMRC) 1-2) and severe to very severe (mMRC 3-4)) using the mMRC dyspnoea scale. Effect size (ES) was computed as estimates of responsiveness. The SGRQ demonstrated greater responsiveness by total sample (SGRQ, ES = 0.87; CAT, ES = 0.75) and for the mMRC 3-4 category (SGRQ, ES = 0.91; CAT, ES = 0.76) on completion of PR. At 28-week follow-up, overall comparable responsiveness of the CAT and SGRQ was identified by total sample (SGRQ, ES = 0.75; CAT, ES = 0.74) and by severity of dyspnoea category. The symptom, impact and activity domains of the SGRQ showed good responsiveness, with greater ESs obtained overall for the mMRC 3-4 category. On completion of PR, the SGRQ demonstrates a greater responsiveness with COPD patients, especially in relation to the mMRC 3-4 category, while both the CAT and SGRQ show comparable responsiveness on follow-up.
