Abstract
OBJECTIVE: To investigate the association between preoperative serum levels of albumin (ALB) and alkaline phosphatase (ALP) with postoperative outcome in colorectal cancer (CRC) patients. METHODS: A thorough literature search was conducted across Embase, PubMed, and Cochrane Library databases, identifying 20 eligible studies encompassing 61,296 participants. Studies were primarily observational and case-control in nature, with some randomized controlled trials also included. The random effects model was utilized to synthesize the effect sizes, while study quality was appraised using the Newcastle-Ottawa Scale and the Cochrane Risk of Bias Assessment Tool. RESULTS: Findings revealed that CRC patients with preoperative ALB levels below 3.5 g/dl were at an elevated risk for postoperative complications (OR = 2.56, 95% CI: 2.12-3.08), increased mortality (OR = 4.54, 95% CI: 2.02-10.20), and a poorer prognostic survival risk (HR = 2.09, 95% CI: 1.58-2.77). Additionally, elevated ALP levels were associated with a higher risk of poor overall survival (HR = 1.67, 95% CI: 1.44-1.94). However, publication bias was noted in some studies. CONCLUSION: Preoperative hypoalbuminemia and elevated ALP levels are significantly linked to adverse postoperative events and reduced survival in CRC patients, suggesting their potential as prognostic biomarkers.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
