Heterogeneous impact of health insurance on children's nutritional status: insights from Instrumental Variable Quantile Regression (IV-QR) approach.
Article in Health economics review, 2026. 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
objectiveEmpirically, this study focuses on the impact assessment of health insurance uptake on the nutrition of kids under five with special attention to variation in wealth level in Pakistan. Theoretical frameworks argue that health insurance provides a safety net against poor health outcomes.
methodsWe analyzed 4,499 children from the Pakistan Demographic and Health Survey (2017-18) using Instrumental Variable Quantile Regression (IV-QR) along with logistic and probit models as bassline, with internet access and distance to health facility as instruments. This approach addresses endogeneity while examining heterogeneity across the nutritional distribution.
resultsThe outcomes of the study are based on probit and logistic estimations. Health insurance in general and the Sehat Sahulat scheme in particular among the poor and most wealthy people in Pakistan greatly increases the positive health outcomes and nutrition of children. The Sehat Sahulat scheme of health insurance coverage of the malnourished children in the low economic class in rural and urban Pakistan provides substantial protection from malnutrition. The IV-QR results reveal that health insurance significantly reduces child malnutrition only for the poorest three wealth quintiles (Q1: OR = 0.64, p < 0.01; Q2: OR = 0.75, p < 0.01; Q3: OR = 0.41, p < 0.01), with no significant effect for wealthier households. The Sehat Sahulat program shows protective effects exclusively for low-income groups, confirming effective targeting. This study assesses the impact of health insurance uptake on child nutrition among children under five in Pakistan, with particular attention to variation across wealth groups.
conclusionThe Sehat Sahulat program effectively targets vulnerable populations, but persistent geographic disparities indicate that insurance alone is insufficient. Policymakers should expand coverage while investing in complementary sanitation, education, and region-specific interventions.
