Effectiveness and Safety of Indomethacin versus Ibuprofen for the Treatment of Patent Ductus Arteriosus in Preterm Infants
Bibliographic record
Abstract
OBJECTIVE: To compare the incidence of medical closure of patent ductus arteriosus (PDA) and adverse events (acute renal dysfunction, necrotizing enterocolitis, spontaneous intestinal perforation, and gastrointestinal bleeding) between preterm infants who received indomethacin and ibuprofen for the treatment of PDA. STUDY DESIGN: A retrospective comparative effectiveness evaluation study was conducted on preterm infants (≤32 weeks) who received indomethacin or ibuprofen for treatment of symptomatic PDA. RESULTS: Of the 124 eligible infants, 54 received indomethacin and 70 received ibuprofen. The overall incidence of medical PDA closure with indomethacin was 37/54 (68.5%) as compared with 42/70 (60%) in the ibuprofen group (p = 0.32). The proportion of infants with surgical PDA ligation was similar between the two groups (18.5% in both the groups). There was no difference in the incidences of acute renal dysfunction, necrotizing enterocolitis stage ≥ 2, spontaneous intestinal perforation, and gastrointestinal bleeding between indomethacin and ibuprofen groups. CONCLUSION: Ibuprofen is as effective as indomethacin in the treatment of symptomatic PDA in preterm infants. This study also shows that both agents have similar adverse effects and the choice of one agent over the other should be based on local availability and dosing preference.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
