A randomized double‐blind controlled trial of phosphorylcholine‐coated tympanostomy tube versus standard tympanostomy tube in children with recurrent acute and chronic otitis media
Bibliographic record
Abstract
OBJECTIVE: To compare the postoperative complication rates of phosphorylcholine-coated fluoroplastic tympanostomy tubes versus uncoated fluoroplastic tympanostomy tubes. METHODS: A prospective randomized double-blind controlled trial in children with recurrent acute otitis media and chronic otitis media with effusion; 240 children were randomized to receive a phosphorylcholine-coated tube in one ear and an uncoated tube in the other. Postoperatively, patients were assessed at 2 weeks and 4, 8, 12, 18, and 24 months to ascertain the incidence of otorrhea, tube lumen blockage, and early extrusion. RESULTS: Out of 240 children, 5 withdrew and 16 were lost to early follow-up. The mean age was 43.8 months. There were no statistically significant differences in the incidence of postoperative otorrhea, tube blockage, and extrusion. CONCLUSIONS: Phosphorylcholine-coated fluoroplastic ventilation tubes do not offer any advantages over uncoated standard fluoroplastic tympanostomy tubes.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
