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
The rising prevalence of caesarean sections (C-sections) in India, surpassing the World Health Organization's recommended rate of 10-15%, has become a significant public health concern. This study aims to analyze the patterns and spatial clustering of C-sections across India's states and districts, utilizing data from the National Family Health Survey (NFHS-4 and NFHS-5). Spatial autocorrelation analysis was applied to summarize the extent to which districts with similar proportions of C-sections tend to occur next to each other, forming spatial clusters. This was done using Global Moran's I index for the fourth and fifth rounds of the National Family Health Survey (NFHS) data conducted in 2015-16 and 2019-21, respectively. LISA cluster maps were produced to test for global spatial autocorrelation, and the Getis-Ord General G statistic was used to test for local clustering. Our research reveals a substantial increase in caesarean deliveries, from 17.2% in NFHS-4 (2015-16) to 21.5% in NFHS-5 (2019-21). This trend is more pronounced in rural areas, challenging previous assumptions about urbanization as a primary driver. We observed marked disparities between public and private healthcare facilities, with private hospitals showing significantly higher rates of caesarean births. Public hospitals exhibited clustering in southern India and parts of northern India, while private facilities showed clustering along the eastern coast and in northeastern regions. Global Moran's I and Getis-Ord General G statistics confirmed significant spatial autocorrelation and clustering (p < 0.01) for both public and private facilities. This study highlights the complex interplay of factors influencing caesarean section rates, including healthcare access, institutional policies, and the urban-rural differential. It underscores the need for targeted interventions and policy adjustments to address the disproportionate increase in caesarean deliveries.
