Association between meat and fish intake and kidney stone risk: a cross-sectional food frequency questionnaire study in a Chinese population.
Article in Frontiers in nutrition, 2026. 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
Background: Dietary factors, particularly meat and fish intake, may influence kidney stone formation, but evidence in the Chinese population is limited. Objective: To investigate the association between various types of meat and fish consumption and kidney stone prevalence using a food frequency questionnaire (FFQ). Methods: A cross-sectional study was conducted with 830 participants (299 kidney stone patients, 531 controls) using online and hospital-based FFQs. Logistic regression models assessed associations, adjusting for confounders. Results: Pork intake showed a non-linear association with kidney stone status. Compared with the lowest intake group, the highest pork intake group was associated with higher odds of kidney stones (OR = 3.321, 95% CI: 1.094-10.044), whereas the highest sea fish intake group was associated with lower odds (OR = 0.331, 95% CI: 0.115-0.936). Processed meat intake was not significantly associated with kidney stone status after adjustment. Conclusion: Pork consumption is positively associated with kidney stone, and sea fish intake is inversely associated with kidney stone in the Chinese population.
