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
Chronic cerebral hypoperfusion (CCH) is a crucial mechanism causing vascular cognitive impairment (VCI). Choline is metabolized by gut microbiota into trimethylamine N-oxide (TMAO), a risk factor of cardiovascular diseases and cognitive impairment. However, the impact of choline-TMAO pathway on CCH-induced VCI is elusive. We performed a cross-sectional clinical study to investigate the relationship between the choline-TMAO pathway and cognitive outcome and used a bilateral common carotid artery occlusion rat model to explore the effect of a choline-rich diet on cognition and underlying mechanisms. Plasma choline and TMAO levels were negatively correlated with cognitive scores in CCH patients. A choline-rich diet exacerbated CCH-induced cognitive impairment by encouraging the proliferation of choline-metabolizing bacteria in the gut and subsequent generation of TMAO. The choline-TMAO pathway, mediated by gut microbiota, exacerbates cognitive impairment induced by CCH. Targeted dietary choline regulation based on gut microbiota modulation may ameliorate long-term cognitive impairment.
