Abstract

fetched live from OpenAlex

INTRODUCTION: Spontaneous intracerebral haemorrhage (sICH) is a severe stroke subtype. The effective therapies for patients with sICH are still unclear, and the role of surgical treatment in sICH management is still controversial. Although some large trials did not show that surgery could benefit patients with sICH, some other studies suggested that some specific surgical strategies can have potential benefits to these patients. For a better understanding of the surgical treatment in patients with sICH, it is necessary to conduct a network meta-analysis to compare the effects of medical treatment and different surgical methods comprehensively. METHODS AND ANALYSIS: This protocol has been reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Related studies until August 2018 will be searched in the following databases: PubMed, Embase, Scopus, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP and Wanfang. Randomised controlled trials and non-randomised prospective studies comparing at least two different interventions in patients with sICH will be included. Quality assessment will be conducted using Cochrane Collaboration's tool or Newcastle-Ottawa Scale based on their study designs. The primary outcome will be functional outcome and the secondary outcome will be mortality. Pairwise and network meta-analysis will be conducted using STATA V.14 (StataCorp, College Station, Texas, USA). Mean ranks and the surface under the cumulative ranking curve will be used to evaluate every intervention. Statistical inconsistency assessment, subgroup analysis, sensitivity analysis and publication bias assessment will be performed. ETHICS AND DISSEMINATION: Ethics approval is not necessary because this study will be based on publications. The results of this study will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42018112239.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
