Association between spicy food consumption and the risk of non-alcoholic fatty liver disease/metabolic dysfunction-associated steatotic liver disease and liver fibrosis.

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
Introduction: Evidence suggested that capsaicin may protect against steatotic liver disease (SLD), but these findings lack validation in population-based studies. This research aimed to explore the association between spicy food consumption and the risk of non-alcoholic fatty liver disease (NAFLD)/metabolic dysfunction-associated steatotic liver disease (MASLD) and liver fibrosis. Methods: A total of 23,666 participants aged 25 to 60, free from NAFLD, MASLD, and liver fibrosis, were recruited from a multi-center physical examination database in Shijiazhuang, Hebei Province, China, between 2011 and 2024. Cox proportional hazards regression model assessed the association between spicy food consumption and incident NAFLD/MASLD and advanced liver fibrosis. Restricted cubic spline (RCS) functions estimated the dose-response relationship. Subgroup and sensitive analyses evaluated heterogeneity based on various characteristics, while sensitivity analyses tested the robustness of results. Results: There were 42.2% of participants who reported consuming spicy food at least once per week. In this cohort study, a total of 7,965 patients with NAFLD and 7,311 patients with MASLD were identified after a median follow-up period of 12.6 years. Those who consumed spicy food more than once a week had a significantly lower risk of NAFLD/MASLD compared to non-consumers, indicating a dose-response relationship. However, this association was not observed in advanced liver fibrosis. Conclusion: Weekly spicy food consumption was inversely associated with risk of incident NAFLD/MASLD, but not advanced liver fibrosis.
