Effect of sevoflurane versus propofol on immune inflammation in patients undergoing endovascular coiling of cerebral aneurysm.
Observational study in BMC anesthesiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06666959 (Comparison of the Neuroprotective Effect of Sevoflurane Versus Propofol in Patients Undergoing Endovascular Coiling of Cerebral Aneurysm), which is not on this 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.

Abstract
backgroundThe objective of this study was to determine whether sevoflurane or propofol would affect the immune inflammation response and neuroprotective potential after endovascular coiling for cerebral aneurysms.
methodsThis prospective cohort study enrolled 80 patients with aneurysmal subarachnoid hemorrhage undergoing endovascular coiling. Patients were divided into two groups: the sevoflurane group (n = 40) and the propofol group (n = 40). The primary clinical outcome was the level of anti-inflammatory factor IL-10 after surgery. Neuroprotection was assessed through neuronal injury marker S100-β and the balance between pro- and anti-inflammatory cytokines, while delayed cerebral ischemia (DCI) was evaluated as a clinical outcome measure of ischemic brain injury. Blood samples were collected at admission (T0) and 24 h postoperatively (T1) to measure neuroinflammatory biomarkers (IL-10, IL-1β, IL-6, IL-8, TNF-α, and S100-β). Given baseline imbalances in IL-8 and TNF-α between groups, we employed analysis of covariance (ANCOVA) with baseline values as covariates, and ΔT1-T0 to account for repeated measures and within-subject correlations.
resultsThe T1/T0 ration of L-10, IL-1β, IL-6, IL-8, TNF-α, and S100-β was 1.00(0.62, 2.86), 1.00(0.62, 2.86), 3.42(0.36, 17.4), 1.42(0.34, 12.14), 1.29(0.57, 7.75), 1.12(0.25, 2.76), respectively in propofol group and 1.00(0.80, 2.64), 1.00(0.65, 2.82), 2.70(0.31, 31.75), 1.78(0.37, 53.60), 1.34(0.44, 13.31), 1.11(0.08, 12.26), respectively in sevoflurane group (P = 0.293, 0.072, 0.810, 0.939, 0.939, and 0.722). Postoperative outcomes including GCS, incidence of DCI related infarcts (propofol 12.5% vs. sevoflurane 15.0%, P = 0.747), and length of hospital stays were similar between groups. However, the sevoflurane group had higher hospital costs compared to the propofol group (170,947 ± 4,921 vs. 149,817 ± 6,097 yuan, P = 0.031).
conclusionsBoth sevoflurane and propofol demonstrated comparable effects on systemic inflammatory biomarkers, neuronal injury markers, and DCI incidence in patients undergoing endovascular coiling for cerebral aneurysms after adjusting for baseline differences. The study indicates that the impact of anesthesia on immune inflammation response, neuronal injury marker, and early clinical events may be limited, and other factors such as patient characteristics and surgical variables may play a more significant role.
