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

backgroundThis trial aimed to evaluate the efficacy and safety of roflumilast for treating Chinese patients with chronic obstructive pulmonary disease (COPD).

methodsA total of 120 patients with COPD were recruited and were randomly divided into 2 groups (an intervention group and a placebo group) at a 1:1 ratio. Patients received either roflumilast or placebo 500 μg once daily for a total of 12 months. The primary outcome was lung function, measured by the change from baseline of forced expiratory volume in 1 second (FEV1), FVC = forced vital capacity (FVC), and FEF25-75%. The secondary outcome measurements included the quality of life, measured with the St. George's Respiratory Questionnaire (SGRQ). All outcomes were measured at the end of 12-month treatment and 3-month follow-up after the treatment. In addition, adverse events (AEs) were also recorded during the treatment period.

resultsFEV1, FVC, FEF25-75%, and SGRQ were significantly better in the intervention group than those in the placebo group at the end of 12-month treatment and 3-month follow up after treatment. Moreover, AEs were much higher with roflumilast than placebo in this study.

conclusionsThe findings suggest that roflumilast has promising effect to improve lung function in Chinese population with COPD.
