Association between numbing-spicy related dietary behavior and hyperuricemia in a Southwestern Chinese population.

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: The consumption of numbing-spicy foods is highly prevalent in southwestern China. However, existing studies examining the relationship between such dietary patterns and disease risk have primarily focused on spicy food intake, with limited attention given to the "numbing" component. This study therefore aimed to systematically investigate the association between both numbing and spicy food intake and hyperuricemia. Methods: All data were derived from the China Multi-Ethnic Cohort (CMEC) study in Rongchang district, Chongqing Municipality, a representative area of southwestern China with high prevalence of numbing-spicy food consumption. Information on numbing and spicy food intake were collected using a standardized questionnaire. The associations between numbing/spicy food consumption and hyperuricemia were evaluated using multivariable logistic regression models and restricted cubic spline analyses. Subgroup analyses were further conducted across diverse demographic and clinical characteristics. To assess potential combined relation, both multiplicative and additive interaction analyses were performed. In addition, mediation and sensitivity analyses were undertaken to assess the robustness of the findings. Results: A total of 2,265 participants aged 30-60 years were included in the analysis. The mean age was 45.21 years (SD = 7.84), and the overall prevalence of hyperuricemia was 13.20%. After adjustment for potential confounding factors, the combined intake of numbing and spicy foods were positively associated with hyperuricemia, with an odds ratio (OR) of 2.689 (95%CI: 2.045-3.536, Conclusion: These findings contribute new evidence regarding the link between numbing-spicy food intake and hyperuricemia, extending prior research that has focused primarily on spicy food consumption alone. Accordingly, future investigations into the dietary etiology of hyperuricemia in southwestern China should move beyond treating spicy food intake as an isolated exposure and the joint effects of characteristic numbing-spicy dietary behaviors and their associated culinary context on the prevalence of hyperuricemia should be systematically considered.
