Abstract BackgroundAnaemia in pregnancy remains prevalent in Nepal and causes severe adverse health outcomes.Methods This non-blinded cluster-randomized controlled trial in the plains of Nepal has two study arms: 1) Control: routine antenatal care (ANC); 2) Home visiting, iron supplementation, Participatory Learning and Action (PLA) groups, plus routine ANC. Participants: Women in 54 non-contiguous clusters (mean 2582; range 1299-4865 population) in Southern Kapilbastu district are eligible if they consent to menstrual monitoring, are resident, married, aged 13-49 years and able to respond to questions. After 1-2 missed menses and a positive pregnancy test, consenting women <20 weeks’ gestation, who plan to reside locally for most of the pregnancy, enrol into trial follow-up. Interventions comprise two home-counselling visits (at 12-21- and 22-26-weeks’ gestation) with iron folic acid (IFA) supplement dosage tailored to women’s haemoglobin concentration, plus monthly PLA women’s group meetings using a dialogical problem-solving approach to engage pregnant women and their families. Home visits and PLA meetings will be facilitated by auxiliary nurse midwives.Hypothesis: Haemoglobin of women at 30±2 weeks’ gestation is ≥0.4 g/dL higher in the intervention arm than in the control. A sample of 842 women (421 per arm, average 15.6 per cluster) will provide 88% power, assuming SD 1.2, ICC 0.09 and CV of cluster size 0.27.Outcomes are captured at 30±2 weeks gestation. Primary outcome: Haemoglobin concentration (g/dL). Secondary outcomes: Anaemia prevalence (%), mid-upper arm circumference (cm), Mean Probability of micronutrient Adequacy (MPA) and number of ANC visits at a health facility.Indicators to assess pathways to impact include number of IFA tablets consumed during pregnancy, intake of energy (kcal/d) and dietary iron (mg/d), a score of bioavailability-enhancing behaviours and recall of one nutrition knowledge indicator.Costs and cost-effectiveness of the intervention will be estimated from a provider perspective. Using constrained randomisation we allocated clusters to study arms, ensuring similarity with respect to cluster size, ethnicity, religion and distance to a health facility. Analysis is by intention-to-treat at the individual level, using mixed-effects regression.Discussion: Findings will inform Nepal government policy on approaches to increase adherence to IFA, improve diets and reduce anaemia in pregnancy.Trial registration: ISRCTN 12272130.

Not 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.
