Inpatient Admissions and Re-Admissions in Medicare Beneficiaries Initiating Umeclidinium/Vilanterol or Tiotropium Therapy.
Article in International journal of chronic obstructive pulmonary disease, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Purpose: Patients with chronic obstructive pulmonary disease (COPD) who are hospitalized are more likely to die from their illness and have increased likelihood of re-admission than those who are not. Subsequent re-admissions further increase the burden on healthcare systems. This study compared inpatient admission rates and time-to-first COPD-related inpatient admission among Medicare beneficiaries with COPD indexed on umeclidinium/vilanterol (UMEC/VI) versus tiotropium (TIO). Patients and Methods: This retrospective study used the All-Payer Claims Database to investigate hospital admission and re-admission outcomes in Medicare beneficiaries with COPD with an initial pharmacy claim for UMEC/VI or TIO from 1 January 2015 to 28 February 2020. Inpatient admissions, baseline, and follow-up variables were assessed in patients indexed on UMEC/VI and TIO after propensity score matching (PSM), with time-to-first on-treatment COPD-related inpatient admission as the primary endpoint. Re-admissions were assessed among patients with a COPD-related inpatient admission in the 30- and 90-days post-discharge. Results: Post-PSM, 7152 patients indexed on UMEC/VI and 7069 on TIO were eligible for admissions analysis. The mean (standard deviation [SD]) time-to-first COPD-related inpatient admission was 46.71 (87.99) days for patients indexed on UMEC/VI and 44.96 (85.90) days for those on TIO (p=0.06). The mean (SD) number of inpatient admissions per patient was 1.24 (2.92) for patients indexed on UMEC/VI and 1.26 (3.05) for those on TIO (p=0.49). Proportion of patients undergoing re-admissions was similar between treatments over both 30 and 90 days, excluding a significantly lower proportion of patients indexed on UMEC/VI than those indexed on TIO for COPD-related re-admissions for hospital stays of 4-7 days and 7-14 days, and all-cause re-admissions for stays of 4-7 days. Conclusion: Patients with COPD using Medicare in the US and receiving UMEC/VI or TIO reported similar time-to-first inpatient admission and similar proportion of re-admissions.
