Clinical outcomes of neurosurgical patients during the COVID-19 pandemic: a systematic review and meta-analysis of global data.
Review in Acta neurologica Belgica, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCOVID-19 pandemic has substantially affected neurosurgical care globally through service reorganizations, delayed presentation, alterations in case selection, and limited perioperative resources. However, overall impact of these changes on clinical outcomes in neurosurgical patients remains unclear. Hence, this review evaluated clinical outcomes of neurosurgical patients managed during COVID-19 era compared with pre-pandemic era.
methodsSystematic search of PubMed, Embase, Scopus, Web of Science was conducted from inception of database till March 2026. Pooled effect estimates were calculated using random-effects meta-analysis. Odds ratios (ORs) were used for dichotomous outcomes and weighted mean differences (WMDs) for continuous outcomes. Heterogeneity was assessed using I² statistic.
resultsTwenty studies were included. In the primary pre-pandemic comparison, mortality was significantly higher during the COVID-19 era across 18 studies including 35,639 patients (OR = 1.49, 95%CI 1.20-1.85; I² = 44.7%). Postoperative complications were also increased across 13 studies including 12,174 patients (OR = 1.44, 95%CI 1.04-1.98; I² = 78.5%). No significant difference was observed for requirement of mechanical ventilation (OR = 1.20, 95%CI 0.81-1.76; I² = 0.0%), whereas length-of-stay findings were inconclusive because of high heterogeneity (WMD = -1.46 days, 95%CI -3.19 to 0.28; I² = 85.8%).
conclusionsNeurosurgical patients managed during the COVID-19 era had higher mortality and postoperative complication rates than those treated before the pandemic. These findings highlight the vulnerability of neurosurgical care systems to large-scale health-system disruption and underscore the need for resilient strategies to ensure timely and safer neurosurgical care during future disruptions.
