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

Purpose: The Montreal Cognitive Assessment (MoCA) is a validated screening tool for cognitive impairment (CI) in surgical populations that assesses multiple cognitive domains. The primary objective of this report was to characterize preoperative domain-specific performance on the MoCA in older surgical patients. The secondary objectives were to explore preoperative characteristics and adverse outcomes associated with poorer domain-specific performance. Methods: This was a post hoc analysis of the Detection of Cognitive Impairment (Detect CI) study. The MoCA was administered preoperatively to assess seven cognitive domains: executive/visuospatial function, naming, attention, language, abstraction, delayed recall, and orientation. It was scored out of 30, with higher education-adjusted MoCA scores indicating better cognitive performance and scores Results: The 382 participants (median age, 73 years [IQR, 68, 77]; 58% female) had a mean MoCA score of 25.9 Conclusions: This analysis characterized preoperative domain-specific performance on the MoCA in older adults, with participants screening positive for CI exhibiting poorer performance across all cognitive domains. Exploratory findings suggested that orientation difficulties may be associated with early adverse outcomes, with postoperative delirium showing the most robust association. Supplementary Information: The online version contains supplementary material available at 10.1007/s44254-026-00181-2.
