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

backgroundGlobal Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines recommend triple therapy (TT) for chronic obstructive pulmonary disease (COPD) patients based on severity. TT utilization by severity is infrequently studied in real-world settings and may deviate significantly from current clinical recommendations. This study describes prescribing pathways to TT among patients with COPD in the United States.

methodsThis study analyzed Geisinger Health System electronic medical records from 1 January 2004 to 30 November 2016. Two retrospective cohorts of COPD patients were included: (1) incident COPD, and (2) incident TT users. COPD treatment patterns, including time to TT, were summarized. Time to TT was estimated using Kaplan-Meier methods. Predictors of the relative hazard for TT among incident COPD patients were estimated using Cox proportional hazards regressions.

resultsIncident COPD and TT cohorts included 57,141 and 8173 patients, respectively. TT was used by 9.6% of incident COPD patients. In the year before TT, 34.3% of incident TT patients received treatment combinations recommended before TT according to GOLD recommendations, which mainly included: long-acting muscarinic antagonists (LAMAs), long-acting beta agonists (LABAs) + LAMAs, and inhaled corticosteroids  + LABAs. Among incident TT patients, median time from COPD diagnosis to TT exceeded 2 years. The hazard for TT over time was associated with lower forced expiratory volume in 1 s values, more frequent exacerbations, current/previous smoking, and comorbid lung conditions such as pulmonary vascular disease, acute respiratory failure, and lung cancer. About 15-20% of the incident TT patients stepped down to a one- or two-drug regimen. Median time to TT discontinuation or step-down were 2 and 9 months, respectively.

conclusionThe study has revealed discrepancies in the treatment of COPD patients between GOLD guidelines and actual clinical practices in the United States. Pathways to TT differed from recommended therapy regimes. Further studies are needed to understand barriers to the use of guideline-recommended TTs by healthcare providers.
