Peripheral Leukocytosis and Clinical Outcomes After Aneurysmal Subarachnoid Hemorrhage.
Article in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundAneurysmal subarachnoid hemorrhage (SAH) has a high morbidity rate. Following SAH, a powerful systemic inflammatory response ensues contributing to delayed neurological deterioration and outcome. The aim of this study is to investigate if peripheral leukocytosis following SAH impacts clinical outcomes.
methodsThis is a retrospective, observational, single tertiary center study of patients with SAH who underwent microsurgical clipping between 2017 and 2020. The study's inclusion criteria were aneurysmal SAH on baseline computerized tomography (CT), age above 18 years, and hospital admission within 72 hours of bleeding. Traumatic SAH, arteriovenous malformations, and mycotic aneurysms were all excluded. On admission, leukocyte counts were recorded. Demographic and clinical variables were compared between the two groups (TLC ≤12,000 and >12,000). The impact of peripheral leukocytes on clinical outcomes in terms of the Glasgow Outcome Score (GOS) was analyzed. Mann-Whitney U test for continuous variable and Fisher exact test or chi-square test for categorical variables were used for calculation of P-value. A P-value of 0.05 or less was considered statistically significant.
resultsAmong 90 patients who underwent clipping of ruptured aneurysms, 40 (44.4%) were anterior communicating artery (ACOMM) aneurysms, and 21 (23.3%) were middle cerebral artery(MCA), and 16 (17.8%) were posterior communicating artery (PCOMM). Clinically 57 patients (63.3%) had a World Federation of Neurosurgical Societies (WFNS) grade 1, 17 patients (18.9%) had a grade 2, four patients (4.4%) had a grade 3, and two patients (2.2%) had a grade 4. On radiological examination, six patients (6.7%) had fisher grade 1, 23 patients (25.6%) had grade 2, 22 patients (24.4%) had grade 3, and 39 (43.4%) had grade 4 SAH distribution. Clinical results were poor in 30 individuals (33.3 %), but good in 60 patients (66.7 %). On admission leukocytosis (>12,000) was seen among 34 (37.8%). Leukocytosis (>12,000) was associated with poor WFNS grade (>2); however, statistical significance was not seen with clinical outcome in terms of GOS.
conclusionPoor clinical grade of patients following aneurysmal SAH is associated with peripheral leukocytosis; however, peripheral leukocytosis is not associated with poor outcomes.
