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
backgroundIn the context of increased health risks for individuals with underlying conditions due to the coronavirus disease 2019 (COVID-19) pandemic, this study investigated whether dietary improvements differ based on the diagnosis of chronic diseases.
methodsThis study used data from the Korea National Health and Nutrition Examination Survey from 2013 to 2021, including 45,391 individuals aged 19 years and older. Diet quality was assessed by the Korean Healthy Eating Index (KHEI) scores. The samples were stratified into subgroups based on the status and diagnosis of hypertension, type 2 diabetes mellitus, and dyslipidemia. Weighted linear regression was utilized to calculate the β coefficients and β
resultsThe weighted average KHEI score showed a declining trend in 2013-2019 (β, -0.46 [95% CI, -0.55, -0.36]) but an increasing trend in 2020-2021 (β, 1.24 [95% CI, 0.45, 2.02]), indicating a significant change in trend with the onset of the pandemic (β
conclusionDiagnoses of hypertension, type 2 diabetes mellitus, and dyslipidemia appear to be positively associated with dietary improvements. During the COVID-19 pandemic, individuals aware of their chronic conditions were more attentive to their diets than those undiagnosed.
