Exploratory analysis of the association between dietary niacin intakes and nonalcoholic fatty liver disease among US adults: 1999-2018 data analysis from the National Health and Nutrition Examination Survey (NHANES).

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
backgroundPrevious researches have revealed the potential association between dietary niacin intakes and several diseases, but studies assessing the association between dietary niacin intakes and nonalcoholic fatty liver disease (NAFLD) is limited and remains unclear. This study was performed to explore the association.
methodsIn this study, 10,528 participants (male: 5,257) in the 10 National Health and Nutrition Examination Survey (NHANES) cycles (1999-2018) from the NHANES database were selected for the analyses. We built three logistic regression models to explore the independent association between dietary niacin intakes and NAFLD and to explore whether such association exists. Finally, a restricted cubic spline model was applied to simulate the potential nonlinear association between dietary niacin intakes and the occurrence of NAFLD.
resultsThe result of the fully-adjusted model suggested that ln-transformed dietary niacin intakes were significantly associated with the reduced occurrence of NAFLD. The odd ratio (OR) of the model and its 95% confidence interval (CI) were 0.81 (0.73, 0.90). When taking the lowest quartile as a reference, the level of niacin in the highest quartile was associated with decreased prevalence of NAFLD (OR: 0.76, 95% CI: 0.63, 0.91). The restricted cubic spline plot presented a negative dose-response association between levels of daily niacin consumption and the occurrence of NAFLD (
conclusionAccording to the results of this study, dietary niacin intakes may have a negative association with NAFLD, and more well-designed cohort studies are required in the future to confirm the obtained finding.
