The relationship between lipid accumulation products and non-alcoholic fatty liver disease among adults in the North of Iran: a cross-sectional study.
Article in BMC gastroenterology, 2025. 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
backgroundInsights into the relationship between adiposity and lipid metabolism are provided by the lipid accumulation product (LAP) index, which is particularly relevant in the context of non-alcoholic fatty liver disease (NAFLD). Therefore, the purpose of this research was to evaluate the relationship between the LAP index and NAFLD in the Iranian population.
methodsThe current cross-sectional study (n = 3,120) was conducted in the second stage of the Amol Cohort Study. NAFLD was confirmed to use ultrasound imaging. The values of the hepatic steatosis index (HSI) and LAP were obtained using the corresponding equations. Additionally, a multivariate logistic regression was performed to examine the relationship between LAP tertiles and both NAFLD and HSI.
resultsThe findings showed that there was a 1.8% increase in the odds of NAFLD and a 1.6% increase in the odds of HSI for each unit change in LAP score (P < 0.001 for both) in the adjusted model. Also, the analysis based on LAP tertiles found higher odds of NAFLD and HSI in the second tertile (NAFLD: odds ratio (OR) = 2.042, 95% confidence interval (CI): 1.578-2.642, P < 0.001 - HSI: OR = 1.765, 95% CI: 1.283-2.428, P < 0.001) and last tertile (NAFLD: OR = 3.607, 95% CI: 2.665-4.880, P < 0.001 - HSI: OR = 3.406, 95% CI: 2.282-5.083, P < 0.001) of LAP compared to the first tertile in the adjusted model.
conclusionsThe present research provides robust evidence that a higher LAP index is strongly associated with higher odds of NAFLD and hepatic steatosis.
