Associated Factors and Pulmonary Function Outcomes of Preserved Ratio Impaired Spirometry: A Scoping Review.
Article in International journal of chronic obstructive pulmonary disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 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
Background: Preserved ratio impaired spirometry (PRISm) is a common but understudied abnormal pulmonary function state and is strongly associated with poor health outcomes. However, there is a lack of uniformity in defining the factors and pulmonary function outcomes associated with PRISm. Objective: This scoping review aims to elucidate the associated factors and pulmonary function outcomes of PRISm, thereby enhancing healthcare professionals' understanding of PRISm and laying the groundwork for its prevention and treatment. Methods: This scoping review follows the 5-step framework developed by Arksey and O'Malley. Literature on PRISm was systematically searched from databases including PubMed, Embase, CINAHL, the Cochrane Library, Web of Science, CNKI, and Wan Fang, spanning from inception to July 2024. Inclusion and exclusion criteria were applied to enroll relevant studies. Data were extracted, collected, summarized, and reported. Results: A total of 38 studies were included. The analysis revealed that associated factors for PRISm encompass possible pathogenic factors (older age, female, lower education level, smoking, obesity, etc), comorbidity associations (asthma, diabetes, cardiovascular diseases, etc), and disease characteristic factors (disease burden, physical performance, radiological characteristics, etc). The pulmonary function status of the PRISm population is unstable, making progression to airflow obstruction (AFO) more likely than in the normal population. PRISm exhibits multiple subgroups (incident or stable PRISm, definite PRISm or PRISm with AFO, non-restrictive or restrictive PRISm, etc) and significant differences exist in pulmonary function outcomes among different subgroups. Conclusion: This scoping review offers a more comprehensive understanding of PRISm. It is recommended that future research focus on a deeper investigation of the pulmonary function of PRISm, elucidating its pathophysiological characteristics, and proposing new strategies for its prevention and treatment. Furthermore, more research is needed in low-income and middle-income economies to understand PRISm comprehensively.
