Which GOLD B patients progress to GOLD D with the new classification?
Article 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. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
backgroundThe 2017 GOLD guidelines revised assessment of COPD by eliminating the FEV
aimFirst, we explored the redistribution of 2011 GOLD groups by reference to the 2017 GOLD criteria. Second, we investigated the characteristics of GOLD B patients and the natural course of GOLD B patients according to the 2017 GOLD guidelines.
methodsIn total, 2,010 COPD patients in the Korean COPD Subgroup Study cohort were analyzed at baseline and 1 year after enrollment.
resultsThe 2011 GOLD C patients were redistributed to the 2017 A (64.5%) and C (35.4%) groups. The 2011 GOLD D patients were redistributed to the 2017 B (61.6%) and D (38.6%) groups. The GOLD B patients constituted 62.7% of all patients according to the 2017 classification. Such patients exhibited higher % predicted FEV
conclusionSevere symptoms, poorer health status, and greater airflow limitation increased patients' risk of exacerbation and progression from group B to group D when the 2017 GOLD criteria were applied.
