Tests. Continuous variable correlations had been investigated with Pearson’s bi-variate correlation. Threshold of statistical significance was viewed as p 0.05. two.5. The Prospective Source of Bias and Study Size We addressed no missing information given that incomplete records had been excluded. A possible source of bias is anticipated to derive in the exiguity of the sample, which nevertheless, in regard to the endpoints selected, presents a fantastic post hoc statistical estimated energy (difference among two independent indicates; 1 – = 0.9488 for 0.05 and impact size 0.5), thus providing particularly trustworthy conclusions. The informed consent was approved by the Institutional Assessment Board of our institution (IRB 6168 Prot. 0935/2020). Before the surgical process, all of the individuals gave informed written explicit consent following suitable data. Data reported in the study have already been absolutely anonymized. For statistical evaluation, information collection, and analysis of final results we have received help in the Neurosurgical Division of Turin, Italy directed by Prof. D. Garbossa. No treatment randomization has been performed due to the study’s retrospective nature. This study is consistent with all the Helsinki Declaration of ethical principles for medical research on humans. three. Final results 3.1. Descriptive Information The final cohort consisted of 340 patients (102 males and 238 females–70 of the population) respecting the F: M ratio reported in the literature of 2:1 [1,2]. The typical age was 60.38 13.56 years (min: 20, max: 90); Smoking habits and hypertension have been revealed at the time of radiological diagnosis in 98 (28.eight ) and 108 sufferers (31.eight ), respectively. Patient choice is reported in Figure 3. We report the clinical debut for all included cases (Table 1); even though only symptomatic meningiomas or meningiomas huge enough to be evaluated as surgical had been regarded in this collection, along with a significant percentage of sufferers (14 patients, 13.2 ) were incidentally diagnosed right after investigations for other pathologies. Within a final division in the key Group A, there had been 117 giant meningiomas (34.4 ) and, in Group B, there were 223 medium/large meningiomas. The two subgroups didn’t present remarkable variations in the age/sex differences. Clinical debut, presence of seizure (p = 0.76), smoking habits (chi-square = 1.362; Df = 1; p = 0.24), and hypertension (chi-square = 1.four; dF = 1; p = 0.24) weren’t significantly associated. The comorbidity status measured as CCI did not reveal significant variations between groups.
