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

Purpose: Inappropriate use of an inhaled corticosteroid (ICS) for COPD has clinical and economic disadvantages. This retrospective analysis of The UK Health Improvement Network (THIN) database identified factors influencing treatment escalation (step-up) from a long-acting muscarinic antagonist (LAMA) to triple therapy (LAMA + long-acting β-agonist-ICS). Secondary objectives included time to step up from first LAMA prescription, Global Initiative for Chronic Obstructive Lung Disease (GOLD) grouping (2011/2013, 2017), and Medical Research Council (MRC) grade prior to treatment escalation. Materials and methods: Data were included from 14,866 people ≥35 years old with a COPD diagnosis (June 1, 2010-May 10, 2015) and initiated on LAMA monotherapy. The most commonly used LAMA at baseline was tiotropium (92%). Results: Multivariate analysis (10,492 patients) revealed that COPD exacerbations, lower forced expiratory volume in 1 second (FEV Conclusion: While the presence of COPD exacerbations seems to be the main driver for treatment escalation, according to the 2017 GOLD strategy many patients appear to be overtreated, as they would not be recommended for treatment escalation. Reviewing patients' treatment in the light of the new GOLD strategy has the potential to reduce inappropriate use of triple therapy.
