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
backgroundShift work is associated with irregular dietary habits and poor nutritional intake, increasing the risk of chronic diseases. This study aimed to assess dietary quality and nutritional intake according to shift work status among Korean adult workers.
methodsData from 15 121 adult workers aged ≥20 years from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 2013 and 2021 were analyzed. Dietary quality was evaluated using the Korean Healthy Eating Index (KHEI), and shift work status was determined by self-reported working hours. Associations between shift work and dietary quality were assessed using multivariable logistic regression, accounting for the complex survey design. Stratified analyses by gender were also conducted.
resultsShift workers showed no significant difference in overall dietary quality compared with day workers (odds ratio [OR] = 0.91; 95% CI, 0.80-1.04). However, shift workers more frequently skipped breakfast (OR = 0.78; 95% CI, 0.68-0.89) and consumed fewer fresh fruits (OR = 0.86; 95% CI, 0.75-0.98), vegetables excluding kimchi/pickles (OR = 0.89; 95% CI, 0.79-0.99), and protein-rich foods (OR = 0.87; 95% CI, 0.77-0.99). Conversely, shift workers had better adherence to recommended sodium intake (OR = 1.19; 95% CI, 1.06-1.34). Gender-stratified analysis revealed lower fruit intake among male shift workers and more frequent breakfast skipping and lower fruit/protein intake among female shift workers.
conclusionsAmong Korean adult workers, shift work was associated with unfavorable dietary patterns, characterized by increased breakfast skipping and lower intake of fruits, vegetables, and protein-rich foods. Tailored strategies to improve meal regularity and dietary balance are recommended for managing the health of shift workers.
