The impact of preoperative frailty on perioperative neurocognitive disorders in elderly patients: A systematic review and meta-analysis.
Review in Journal of research in medical sciences : the official journal of Isfahan University of Medical Sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Perioperative neurocognitive disorders (PNDs) were the most common complication in elderly patients undergoing surgery. Early identification of risk factors for PNDs and implementation of preventive measures were critical to improve prognosis. We performed this systematic review and meta-analysis to explore the impact of preoperative frailty on PNDs in elderly surgical patients. Materials and Methods: Systematic searches were performed in PubMed, Embase, and Web of Science. A fixed-effect model in RevMan5.3 software was conducted due to the low heterogeneity. The potential risk bias was assessed through Funnel plot and Egger's test. Sensitivity analysis was used to examine the robustness of the outcomes. Results: Sixteen cohort studies enrolling 4805 elderly patients were qualified for meta-analysis. Pooled results showed that preoperative frailty was linked to the development of PNDs (pooled odds ratio [OR]: 2.40, 95% confidence interval [CI]: 2.05-2.80, Conclusion: Our results demonstrated that preoperative frailty was independently associated with PNDs in geriatric patients undergoing elective surgery.
