Recent trends in the caesarean section rate in Ireland 1999 - 2006
Bibliographic record
Abstract
This paper explores levels and trends in the prevalence of caesarean section delivery in Ireland between 1999 and 2006. Over this period the caesarean section rate in Ireland increased by almost one quarter. Using data from the Irish National Perinatal Reporting System we examine the contribution of maternal, birth/infant and hospital characteristics on the rise in the caesarean section rate over the period. International evidence suggests that earlier gestational age of child, older maternal age at birth, higher socio-economic status of mother and birth within a private hospital all increase the risk of caesarean section. Controlling for changes in the prevalence of these and other risk factors between 1999 and 2006 only explains half of the increase in the caesarean section rate amongst singleton delivery first time mothers. This suggests that changes in physician behaviour over the period may well play a significant role.

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.
