Their study has many strengths. The comprehensive search strategy minimized the chance of publication bias and English-language bias. Explicit selection criteria were used, including studies with randomized allocation; comparison of albumin administration with crystalloid, no albumin, or lower-dose albumin; and an end point of mortality. The investigators selected trials and abstracted data in duplicate. Other criteria for quality assessment of the trials included treatment allocation, crossovers, and blinding. Blinding of whom (clinicians, researchers, outcome assessors, analysts, or patients) and for what purpose ...References1. Wilkes MM, Navickis RJ. Patient survival after human albumin administration.

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.
