How do multiple deprivations in nuanced urban and rural settings affect health differently in South Africa? Evidence from NIDS data, 2017.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
INTRODUCTION/
objectivePrevious research on socioeconomic factors influencing health outcomes has often centred on the urban-rural divide, overlooking the nuanced variations within these categories. This study enhances our understanding by moving beyond traditional comparisons to examine the specific impacts of multiple deprivations on self-rated health across traditional authority areas, rural formal areas, urban informal areas and urban formal areas. By doing so, it captures the unique challenges and health implications associated with varying deprivation levels within these diverse contexts.
methodsWe first constructed the Provincial Index of Multiple Deprivation for each selected region using Wave 5 data from the National Income Dynamics Study, enabling an assessment of the health impacts of multiple deprivations across South Africa. During the estimation of the ordered probit model, collinearity issues emerged. To address this, we applied Principal Component Analysis (PCA) to create independent components which were then incorporated into the model. Self-reported health (SRH) was used as the dependent variable, allowing us to gain valuable insights into the relationship between health and multiple deprivation within these four contexts.
resultsThe study uncovers significant disparities in deprivations, with the most deprived areas being rural formal areas and traditional authorities' areas and the least deprived being the urban formal areas. The PCA variables in the ordered probit model suggest that traditional and rural formal areas soften the effect of multiple deprivations on SRH relative to urban areas. In contrast, informal urban areas enhance the negative effect of multiple deprivation SRH relative to urban formal areas. CONCLUSION/RECOMMENDATIONS: The interaction between multiple deprivation variables and the specific areas examined in this study reveals varying impacts on health. Greater attention should be given to finer geographical characteristics in residential contexts to ensure that interventions are tailored effectively to the specific needs of each area. This focus is particularly important, as the local context may significantly impact health-a fundamental component of life and well-being.
