Association between liver biomarkers and risk of cognitive impairment and dementia: A systematic review and meta-analysis.
Review in Pakistan journal of medical sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Objective: We aimed to systematically examine the literature and conduct a meta-analysis to assess if liver biomarkers like alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT) could be predictors of cognitive impairment and dementia. Methods: Online databases of Scopus, Embase, PubMed, CENTRAL, and Web of Science were searched for all observational studies examining the research question. The last date of the search was August 20, 2024. Results: We selected 13 studies. Pooled analysis showed that there was no significant association between ALT levels or AST levels and risk of cognitive impairment. Meta-analysis showed the higher AST: ALT ratio and higher GGT levels were associated with a statistically significant increased risk of cognitive impairment. Lower ALT levels were associated with a significant increase in the risk of dementia but no significant association was noted with AST or GGT levels. Conclusions: Preliminary evidence indicates that liver biomarkers may have a role in predicting the risk of cognitive impairment/dementia. A high AST: ALT ratio may be linked with an increased risk of cognitive impairment and dementia. Likewise, high GGT and low ALT levels seem to be associated with increased risk of cognitive impairment and dementia respectively.
