Prevalence and Impact of Food Insecurity in Patients Undergoing Pulmonary Function Testing: A Cross-Sectional Study.
Article in CHEST pulmonary, 2025. 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
backgroundFood insecurity (FI), the lack of consistent access to food for a healthy life, affected 13.5% of US households in 2023 and is associated with several chronic diseases. Limited data exist on the relationship between FI and lung health. RESEARCH QUESTION: In this cross-sectional study of adults presenting for pulmonary function testing (PFT), is FI associated with pulmonary function or respiratory symptom burden? STUDY DESIGN AND
methodsWe conducted a cross-sectional study of adults presenting for PFT between March 2018 and January 2023 in a large academic health network in North Carolina. FI was assessed using a validated 2-item questionnaire. Pulmonary function was measured using percent predicted FEV
resultsOf 10,805 patients screened, 17.8% reported FI. Patients with FI were more likely to be younger, female, non-Hispanic Black or Hispanic, to actively smoke, and to reside in socioeconomically disadvantaged areas. FI was associated with lower percent predicted FEV
interpretationOur findings suggest that FI is associated with worse pulmonary function and higher respiratory symptom burden in patients undergoing PFT, highlighting the importance of addressing FI as a social determinant of respiratory health. Further research is needed to explore mechanisms and potential interventions to mitigate the impact of FI on lung health.
