The paradox of food production, expenditure, poverty and stunting in Tanzania: an ecological study design.

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: There have been claims amongst nutrition stakeholders in Tanzania that the food basket regions, are the regions most affected by stunting among children. However, this study could not find evidence that combines food production and stunting levels, to substantiate this claim. Therefore, this study aims to compare data on stunting, food production and consumption within administrative regions of the Tanzania mainland. Methods: The study used an ecological study design to show the relationship between stunting, poverty, food production and food and non-food consumption expenditure across administrative regions in Tanzania mainland. The study used data from three national wide surveys: 2017/2018 Household Budget Survey (HBS), Tanzania National Nutrition Survey (TNNS) 2018 and Agriculture Statistics for Food Security report 2018/2019. Results: The study showed that there is a positive relationship between the prevalence of stunting and food production (r=0.43, p=0.03), while there is a negative relationship between stunting and the level of both the average monthly household food consumption expenditure (r = -0.51, p = 0.01) and average monthly household non-food consumption expenditure (r = -0.51, p = 0.01). Furthermore, some regions with high stunting prevalence (e.g., Njombe) were found to have relatively low basic-needs poverty rates. Conclusion: The study found a positive relationship between food production and the prevalence of stunting using data across regions in mainland Tanzania. This is an indication that regional food production may not entail nutrition outcomes, hence a call for more advocacy on nutrition-sensitive agriculture.
