Abstract
OBJECTIVE: To evaluate the efficacy of suction drainage in preventing postoperative hematoma formation in thyroid surgery. METHODS: We conducted a meta-analysis using only randomized controlled trials in which the incidence of post-thyroidectomy hematoma was compared directly in patients with and without suction drains (eight studies since 1980; N = 944). The odds ratio (OR) with respective confidence intervals (CIs) using the fixed effects model was reported. We used an OR < 1.0 as being in favour of treatment (ie, the use of suction drains). RESULTS: In our meta-analysis, there was no statistically significant difference between the rates of post-thyroidectomy hematoma whether or not suction drains were used when the results were combined using a fixed effects model (OR 1.04, 95% CI-1.93), with p = .90. In this comparison, a fixed effects model was used rather than a random effects model because there was no statistically significant heterogeneity (chi2 = 6.26, p = .28). CONCLUSIONS: We conclude that the use of suction drains in thyroid surgery to prevent postoperative hematoma is not evidence based.

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
