1 · What the graph read from it

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.

2 · The registry

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: Cognitive impairments, including mild cognitive impairment (MCI) and dementia, significantly affect patients' daily functions and quality of life, contributing to a substantial societal and economic burden. The role of uric acid in cognitive function is controversial, with some studies suggesting protective effects, while others indicate increased risk of cognitive decline. Methods: A total of 1,098 participants with an average age of 69 years were included in the study. Cognitive function was assessed using the Mini-Mental State Examination. Hyperuricemia was defined as blood uric acid concentrations >420 μmol/L. Logistic regression and restricted cubic spline analysis were performed to assess the association between hyperuricemia and cognitive impairment, including MCI and dementia. Results: Hyperuricemia was associated with a lower risk of cognitive impairment (OR = 0.51, 95% CI = 0.31-0.80) and MCI (OR = 0.39, 95% CI = 0.21-0.69), particularly in individuals younger than 70 years, males, and those without hypertension or diabetes. No significant association was found between hyperuricemia and dementia (OR = 0.94, 95% CI = 0.44-1.89). There is no evidence of a non-linear relationship between hyperuricemia and cognitive impairment. Conclusion: Hyperuricemia appears to have a protective effect on cognitive function, particularly in reducing the risk of MCI, but not dementia, in specific populations.
