Association between weight fluctuation and the risk of metabolic dysfunction-associated steatotic liver disease.
Article in World journal of hepatology, 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
backgroundThe global incidence of metabolic dysfunction-associated steatotic liver disease (MASLD) has increased in recent years. It has already been demonstrated that exercise and weight change are associated with the occurrence of MASLD; however, the association between weight fluctuation caused by different exercise intensities and the risk of MASLD remains to be studied.
aimTo investigate the impact of weight fluctuation and physical activity intensity on the risk of MASLD prevalence.
methodsData from the National Health and Nutrition Examination Survey database including five cycles from 2009 to 2018 were analyzed. The model included variables such as age, sex, and poverty income ratio. Weighted multivariate logistic regression was used to examine the influence of different weight fluctuation patterns within the two time intervals on the prevalence of MASLD. Nonparametric restricted cubic spline curves were used to analyze the non-linear relationship between net weight change and MASLD prevalence.
resultsAmong 3183 MASLD cases, the risk of MASLD increased with age for individuals transitioning from non-obese to obese or maintaining obesity, with odds ratio (OR) changing from 8.91 (95%CI: 7.40-10.88) and 11.87 (95%CI: 9.65-14.60) at 10 years before baseline to 9.58 (95%CI: 8.08-11.37) and 12.51 (95%CI: 9.33-16.78) at 25 years. Stable obesity correlated with age-dependent MASLD prevalence escalation, whereas increased physical activity attenuated MASLD risk in this group, with an OR changing from 13.64 (95%CI: 10.59-17.57) to 6.42 (95%CI: 4.24-9.72). Further analysis of the net weight changes revealed a paradoxical risk elevation with intensified physical activity during different time periods.
conclusionThe risk of MASLD increases in individuals transitioning from non-obese to obese or maintaining obesity. High-intensity physical activity is beneficial for MASLD among individuals with stable obesity.
