Treatment Transitions in Chronic Obstructive Pulmonary Disease: Retrospective Analyses of US and UK Healthcare Databases.
Article in Pulmonary therapy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionPrevious studies have reported that more patients receive inhaled corticosteroid (ICS)-containing therapies than would be expected based on exacerbation history, suggesting overprescribing. We aimed to describe patterns of treatment switching from first (1MT) to second maintenance therapy (2MT) among COPD patients in the US and UK.
methodsWe used healthcare data from the US IBM
resultsOverall, 7028 patients in the US and 2461 in the UK initiated 2MT within a median (IQR) 160.0 (76.0; 335.0) and 218.0 (86.0; 428.0) days after 1MT, respectively. In the US, 33.6% of patients initiating 2MT had no recorded exacerbations in the previous year, whereas 23.1% had one and 43.3% had ≥ 2. In the UK, 54.9% of patients had no recorded exacerbations in the previous year, whereas 20.9% had one and 24.2% had ≥ 2. At 2MT, most patients switched to LAMA/LABA/ICS (26.1%) or LABA/ICS (25.8%) in the US, and LAMA/LABA (39.4%) or LAMA/LABA/ICS (27.8%) in the UK; 62.2% (US) and 47.5% of patients (UK) were prescribed ICS-containing regimens. The most common treatment transition from 1MT to 2MT was LABA/ICS to LAMA/LABA/ICS (13.0%) in the US; and LAMA to LAMA/LABA (32.5%) and LAMA to LAMA/LABA/ICS (14.3%) in the UK.
conclusionsAt 2MT, the proportion of patients on LAMA/LABA/ICS was similar between the US and UK, but treatment pathways were different.
