Dietary one-carbon metabolism nutrients and risk of MASLD progression: a prospective cohort study.
Article in European journal of clinical nutrition, 2026. 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
BACKGROUND/
objectivesThe relationship between one-carbon metabolism (OCM) nutrients (methionine, folate, vitamin B2, vitamin B6, and vitamin B12) and metabolic dysfunction-associated steatotic liver disease (MASLD) remains uncertain. This study aimed to examine the association of dietary intake OCM nutrients intake with liver-related events (LRE) and mortality among individuals with MASLD.
methodsThis prospective cohort study analyzed data from 46,800 participants in the UK Biobank. MASLD was defined using a validated Fatty Liver Index (FLI) ≥ 60. Dietary intake was assessed using a web-based 24-hour dietary recall tool. Participants with a history of cancer or LRE at baseline were excluded. Multivariable Cox proportional hazard models and restricted cubic splines (RCS) were employed to estimate hazard ratios (HRs) and evaluate dose-response relationships.
resultsDuring a median follow-up of 13.3 years, 291 incident LRE cases and 3547 deaths occurred. Higher dietary intakes of several OCM nutrients were associated with lower risks of LRE and mortality, with the strongest evidence observed for vitamin B6. The HRs and 95% CIs of LRE comparing the highest with lowest intake categories were 0.74 (0.53, 1.04) for methionine, 0.66 (0.48, 0.92) for vitamin B6, 0.78 (0.56, 1.08) for vitamin B2, 0.71 (0.51, 0.99) for vitamin B12, and 0.72 (0.52, 1.00) for folate. Similar inverse associations were observed for mortality. RCS analyses indicated an approximately linear dose-response relationship with LRE incidence, whereas the associations with mortality appeared non-linear.
conclusionsHigher dietary intake of OCM nutrients is associated with lower risks of LRE and mortality in populations with MASLD.
