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: Preferences for consuming food items as determinants of food choices are significantly associated with diet- and health-related outcomes in adulthood. Objectives: The aim of the present study was to culturally adapt and investigate the psychometric properties of the Persian version of the food preferences questionnaire (FPQ-adult) among Iranian adults. Methods: This methodological cross-sectional study was conducted among 522 Persian-speaking adults, living in Isfahan, Iran. Translation of the FPQ was performed using forward-backward method. Intraclass correlation (ICC) and Cronbach α were used to assess test-retest reliability and internal consistency, respectively. Construct validity was investigated by using exploratory factor analysis (EFA). Known-group validity was assessed by using independent samples Results: The internal and test-retest reliabilities for the FPQ-adult were in the range of moderate to excellent in all domains (intraclass correlation: 0.62-0.93; Cronbach α: 0.54-0.90). Construct validity led to extraction of 9 factors (fruit, vegetables, snacks, cereals-based dishes, rice and bread, processed dairy products and condiments, animal protein, fresh dairy products, and miscellaneous foods), explaining 41.73% of the total variance. The mean scores of fruits, vegetable, cereals-based dishes, and animal protein dimensions were significantly different between participants with elevated compared with low anxiety and depression scores, indicating good known-group validity. These 4 dimensions showed a significant positive correlation with age. Conclusions: The Persian version of the FPQ-adult demonstrated moderate to excellent test-retest reliability and acceptable to good internal consistency across all domains. The extracted factor structure supported construct validity, and significant differences in food preference dimensions between participants with elevated compared with low anxiety or depression scores confirmed known-group validity. These findings indicate that the Persian FPQ-adult has adequate psychometric properties for assessing food preferences in Persian-speaking community-dwelling adults.
