S100B predicts neurological injury and 30-day mortality following surgery for acute type A aortic dissection: an observational cohort study.
Observational study in Journal of cardiothoracic surgery, 2023. 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
backgroundNeurological injuries are frequent following Acute Type A Aortic Dissection (ATAAD) repair occurring in 4-30% of all patients. Our objective was to study whether S100B can predict neurological injury following ATAAD repair.
methodsThis was a single-center, retrospective, observational study. The study included all patients that underwent ATAAD repair at our institution between Jan 1998 and Dec 2021 and had recorded S100B-values. The primary outcome measure was neurological injury, defined as focal neurological deficit or coma diagnosed by clinical assessment with or without radiological confirmation and with a symptom duration of more than 24 h. Secondary outcome measure was 30-day mortality.
results538 patients underwent surgery during the study period and 393 patients, had recorded S100B-values. The patients had a mean age of 64.4 ± 11.1 years and 34% were female. Receiver operating characteristic curve for S100B 24 h postoperatively yielded area under the curve 0.687 (95% CI 0.615-0.759) and best Youden's index corresponded to S100B 0.225 which gave a sensitivity of 60% and specificity of 75%. Multivariable logistic regression identified S100B ≥ 0.23 μg/l at 24 h as an independent predictor for neurological injury (OR 4.71, 95% CI 2.59-8.57; p < 0.01) along with preoperative cerebral malperfusion (OR 4.23, 95% CI 2.03-8.84; p < 0.01) as well as an independent predictor for 30-day mortality (OR 4.57, 95% CI 1.18-11.70; p < 0.01).
conclusionsWe demonstrated that S100B, 24 h after surgery is a strong independent predictor for neurological injury and 30-day mortality after ATAAD repair.
