Budesonide/Glycopyrrolate/Formoterol Fumarate Metered Dose Inhaler Improves Exacerbation Outcomes in Patients with COPD without a Recent Exacerbation History: A Subgroup Analysis of KRONOS.
Trial report in International journal of chronic obstructive pulmonary disease. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02497001 (A Randomized, Double-Blind, Parallel-Group, 24-Week, Chronic-Dosing, Multi-Center Study to Assess the Efficacy and Safety of PT010, PT003, and PT009 Compared With Symbicort® Turbuhaler® as an Active Control in Subjects With Moderate to Very Severe Chronic Obstructive Pulmonary Disease), which is not on this map.

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.

Abstract
purposeIn the Phase III, 24-week KRONOS study (NCT02497001), triple therapy with budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI) reduced exacerbation rates versus glycopyrrolate/formoterol fumarate (GFF) MDI in patients with moderate-to-very severe chronic obstructive pulmonary disease (COPD) and no requirement for a history of exacerbations. We report a post hoc analysis investigating whether the benefits observed were driven by patients with ≥1 exacerbation in the 12 months prior to the study. PATIENTS AND
methodsPatients received BGF MDI 320/18/9.6 µg, GFF MDI 18/9.6 µg, budesonide/formoterol fumarate (BFF) MDI 320/9.6 µg, or budesonide/formoterol fumarate dry powder inhaler (BUD/FORM DPI) 400/12 µg twice-daily. Post hoc analyses were conducted on exacerbation and lung function results from patients with and without a documented exacerbation in the 12 months prior to the study.
resultsOverall, 74% (1411/1896) of the modified-intent-to-treat (mITT) population had no moderate/severe exacerbations in the 12 months prior to the study. BGF MDI reduced exacerbation rates versus GFF MDI in the prior (58%; unadjusted
conclusionIn patients with or without a history of exacerbations in the 12 months prior to the study, BGF MDI reduced exacerbation rates versus GFF MDI, suggesting results observed in the overall population were not driven by the small subgroup with a prior history of exacerbations.
