Readmission Following Extracranial-Intracranial Bypass Surgery: Risk Factors and Patient Characteristics Using the ACS NSQIP Database.
Article in Neurosurgery practice, 2026. 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
BACKGROUND AND
objectiveUnder select indications, extracranial-intracranial (EC-IC) bypass surgery is performed for intracranial revascularization. This study aimed to identify risk factors for 30-day readmission after EC-IC bypass surgery using data from the American College of Surgeons National Surgical Quality Improvement Program database.
methodsWe conducted a longitudinal analysis of the American College of Surgeons National Surgical Quality Improvement Program database from 2011 to 2020. Patients who underwent EC-IC bypass, identified by current procedural terminology code 61711, were included. The primary outcome was a 30-day readmission. Variables such as age, body mass index (BMI), operation time, total length of stay, preoperative duration, sex, race, home discharge status, elective surgery status, diabetes, smoking status, dyspnea, independent status, chronic obstructive pulmonary disease, congestive heart failure, hypertension, dialysis, cancer, chronic steroid use, sepsis, septic shock, emergency surgery status, wound classification, and American Society of Anesthesiologists classification were analyzed. Statistical analysis included univariate and multivariate logistic regression to identify independent predictors of readmission.
resultsAmong 350 patients who underwent EC-IC bypass, 32 (9.1%) were readmitted within 30 days. Univariate analysis revealed that readmitted patients had a significantly higher BMI (35.0 vs 30.0,
conclusionThis study highlights BMI as a significant predictor of 30-day readmission after EC-IC bypass surgery. These findings underscore the importance of preoperative optimization and targeted postoperative care for high-risk patient populations. Future research should focus on prospective studies to validate these findings and explore additional factors contributing to readmission, aiming to improve patient outcomes and reduce health care costs associated with readmissions.
