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

Introduction: Age-related decline in visual processing has been observed in association with reduced orientation selectivity and decreased signal-to-noise ratios in the primary visual cortex (V1). Elevated noise correlations between neurons are associated with impaired visual discrimination in aging; however, less is known about therapeutic interventions that could preserve visual cortical function during aging. In this study, we investigated the effects of metformin treatment on age-related changes in visual processing and neuronal correlations in V1. Methods: We conducted Results: Discussion: Metformin treatment effectively ameliorated these deficits through enhanced GABAergic signaling; however, the broader therapeutic mechanisms across sensory systems remain unclear. In this study, we demonstrate that metformin preserves visual function by restoring excitatory-inhibitory balance, suggesting a promising approach for age-related sensory decline.
