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

backgroundCurrent evidence suggests that roflumilast is efficacious in treating COPD, especially in preventing the acute exacerbation of COPD.

objectivesThis study was designed to evaluate the clinical effects and safety of roflumilast in the treatment of stable COPD using randomized clinical trial (RCT) data.

methodsA MEDLINE, EMBASE, and Cochrane Controlled Trials Register search was carried out. RCTs reporting the treatment effects of roflumilast in COPD were identified. Relevant data were extracted and a meta-analysis was performed.

resultsA total of nine articles and 13 RCT studies were identified. Overall, 29.1% of the subjects in the roflumilast group showed evidence of exacerbation. The corresponding figure was 32.2% in the placebo group. According to pooled analysis, the use of roflumilast reduced COPD exacerbations in comparison to placebo (odds ratio [OR] =0.82, 95% confidence interval [CI] =0.75-0.9). The quality of life and spirometry were improved. For patients receiving baseline pre-bronchodilators, their average forced expiratory volume in the first second showed evidence of change when they took roflumilast (64.88 mL; 95% CI =54.09-75.66). Those who took placebo showed no evidence of change. Similar result was observed in patients receiving baseline (54.49 mL; 95% CI =44.04-64.94). As for the safety of roflumilast treatment, the overall cumulative incidence of adverse drug reaction was 54.2% in the roflumilast group and 48.2% in the placebo group (OR =1.36, 95% CI =1.13-1.65). The adverse effects included diarrhea, headache, nausea, weight loss, and insomnia.

conclusionThe efficacy of roflumilast in the prevention of acute exacerbation of COPD is obvious. Roflumilast is proved to be able to improve spirometry of COPD patients. The adverse drug reaction did not increase significantly in the roflumilast group compared with the control group. COPD patients can benefit from roflumilast therapy. However, our results are limited by the cohort design of the selected studies and the degree of heterogeneity among them; hence, more randomized trials are needed to further support this conclusion.
