Abstract
( Int J Gynaecol Obstet . 2016;133(3):277–283) Pica, the purposeful consumption of nonfood or non-nutritive substances, is commonly reported in women during the period surrounding childbirth. However, the Diagnostic and Statistical Manual of Mental Disorders-5 does not provide a prevalence estimate for pica, and current prevalence estimates during pregnancy range from 0.007% in Denmark to 92.5% in Nigeria. In this meta-analysis, authors estimated the prevalence of pica in pregnant and postpartum populations and characterized potential contributing factors/moderators.

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
