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
objectivesDelirium, an acute disorder of attention and cognition, is a preventable contributor to poor outcomes in older adults including future cognitive decline. The goal of this study was to examine the cognitive impact of postoperative delirium. DESIGN, SETTING,
participantsA secondary analysis of the randomized clinical trial STRIDE (A Strategy to Reduce the Incidence of Postoperative Delirium in Elderly Patients) which included two hundred hip fracture repair patients was conducted. MEASUREMENTS: Cognitive changes one year after surgery were examined. Modified Clinical Dementia Rating (CDR) and postoperative delirium status were adjudicated by a consensus panel. Delirium Rating Scale-Revised-98(DRS-R-98) was used to measure delirium severity. Data were analyzed using a random-intercept linear spline model, with Mini Mental State Examination (MMSE) and dementia severity (using CDR Sum of Boxes [CDR-SB]), as outcomes.
results36.5% of the overall cohort experienced delirium. When stratified by baseline cognitive status, delirium was associated with a faster rate of decline in MMSE and worsening in CDR-SB in cognitively unimpaired participants, but not in participants with baseline cognitive impairment. We found an estimated delirium associated change in MMSE of 1.52 points and CDR-SB of 1.22 points within one year after surgery associated with postoperative delirium after hip fracture repair in cognitively normal participants.
conclusionsThis study provides evidence that postoperative delirium is associated with a faster rate of cognitive decline, particularly in cognitively unimpaired individuals. This work highlights the importance of delirium prevention and management strategies in improving long-term cognitive outcomes in older adults.
