Clinical benefit of two-times-per-day aclidinium bromide compared with once-a-day tiotropium bromide hydrate in COPD: a multicentre, open-label, randomised study.
Trial report in BMJ open, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
objectiveChronic obstructive pulmonary disease (COPD) is mainly treated pharmaceutically with bronchodilators. The purpose of this study was to evaluate the clinical benefits of two-times-per-day aclidinium bromide (Acli-BID) compared with once-a-day tiotropium bromide hydrate (Tio-QD) in patients with COPD.
designThis study was a multicentre, open-label, randomised study.
settingFourcentres in Kagawa prefecture, Japan. PARTICIPANT: Patients who were diagnosed to have COPD Grade 2-3 according to the Global Initiative for Chronic Obstructive Lung Disease 2015 criteria were enrolled.
interventionsPatients were randomly assigned to receive Acli-BID or Tio-QD at a 1:1 ratio, and followed for 8 weeks. Acli-BID was administered in the morning and night, and Tio-QD was administered in the night. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome was forced expiratory volume in one second area under the curve (FEV
results44 patients were included in this study. FEV
conclusionAcli-BID as with Tio-QD could be one of the therapeutic options for patients with COPD to improve pulmonary function. Also, our results suggest that intervention with bronchodilators enhanced physical activity in patients with COPD. TRIAL REGISTRATION NUMBER: UMIN 000020020.
