The Effectiveness of Nutritional Interventions on Maternal and Childhood Anaemia in Sindh, Pakistan.
Article in Nutrients, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
objectivesIn Pakistan, 41.7% of women of reproductive age and 53.7% of children aged 6-59 months are anaemic. This study aimed to evaluate the effectiveness of a nutritional supplementation programme, underpinned with behaviour change communication and implemented through Lady Health Workers (LHWs), in reducing anaemia among pregnant and lactating women as well as 6-59-month-old children.
methodsThis study used a quasi-experimental design with an intervention and a control group. A total of 2821 and 2410 pregnant and lactating women and 3397 and 3277 children aged 6-59 months participated in the baseline and endline surveys, respectively. The study areas were matched for demographic and economic characteristics, and both had routine public-sector health and nutrition programmes, including iron-folic acid supplementation during pregnancy. The participants in the intervention group received additional nutritional support. Throughout the pregnancy and in the first six months of exclusive breast feeding, women were provided 5 kg (165 g/day) of wheat soya blend (WSB) per month. Children aged 6-23 months received lipid-based nutrient supplements (LNS), and those aged 24-59 months received micronutrient powder. We applied a difference-in-difference (DID) analysis with kernel propensity score matching to assess the impact on anaemia, a secondary outcome of a stunting prevention programme.
resultsMaternal anaemia (both pregnant and breastfeeding women) declined substantially in the intervention areas from 80.4% to 62.6% compared with a smaller reduction in the control areas (80.0% to 72.9%). The DID estimate showed a 10.7-percentage-point (pp) greater decline in maternal anaemia (
conclusionsOverall, the findings suggest that LHWs can effectively reduce maternal anaemia when iron-folic acid supplementation is complemented with WSB and targeted behaviour change communication.
