1 · What the graph read from it

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.

2 · The registry

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

backgroundSon preference remains a key driver of gender inequality in India, yet most studies treat its determinants as uniform across space, obscuring critical subnational variation. Addressing this gap, this study investigates the geographic heterogeneity of son preference and examines how its predictors vary spatially. Data and methods Using district-level data on 102,045 ever married women aged 15-49 from the National Family Health Survey-5 (2019-2021), we applied a spatially explicit analytical framework, including choropleth mapping, Global Moran's I, hotspot analysis, Local Indicators of Spatial Association (LISA) cluster mapping, kriging interpolation, and Geographically Weighted Regression (GWR). The use of GWR was justified by significant spatial non-stationarity (Koenker BP = 32.78, p < 0.001) detected in OLS diagnostics.

resultsSon preference prevalence ranged 8.2%-42.3%. Global Moran's I (0.397, z = 57.86, p < 0.001) confirmed significant clustering. OLS identified five significant predictors: parity 2, no mass media exposure, household size 5-8, illiterate mothers, and younger maternal age, explaining 64% variance. GWR demonstrated superior fit (AICc: 4459.98 vs 4478.46; adjusted R

conclusionSon preference is a spatially embedded social process, shaped by localized patriarchy, economy, and institutions. Geographically targeted, gender-transformative policies such as conditional incentives for girls' schooling and localized media campaigns effectively address the structural devaluation of daughters.
