ArticleTherapeutic advances in respiratory disease
Development and validation of a multimodal risk prediction model for early COPD progression: a retrospective study integrating clinical, functional, and CT radiomic features.
Article in Therapeutic advances in respiratory disease. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundEarly identification of rapid progression in patients with preserved ratio but chronic cough remains challenging.
objectiveTo develop and validate an integrated multimodal prediction model that combines clinical phenotypes, small airway function indices, and chest CT quantitative features for stratifying progression risk in individuals with preserved ratio, chronic cough, and early COPD features.
designRetrospective cohort study with external validation.
methodsIn this retrospective cohort study of 408 participants with chronic cough (⩾3 months) and preserved spirometry (FEV
resultsMultivariable analysis confirmed small airway dysfunction and mucus plug burden as independent predictors of accelerated FEV
conclusionWe developed and validated a robust multimodal prediction model that accurately stratifies progression risk in individuals with preserved ratio, chronic cough, and early COPD features. This tool facilitates personalized risk assessment and holds promise for guiding precision management strategies to improve outcomes in this high-risk population.
