Farming Systems, Food Security, Dietary Intakes, and Nutrition Status Among Young Children in Rural Tanzania Before and After Harvest.

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
Subsistence farming households are at risk of food insecurity and poor nutritional status due to dependence on farm production for consumption. This study aimed to examine the relationship between household farming systems, food security and infant nutrition status pre- and post-harvest. Households with mothers and infants and young children < 24 months were recruited from rural villages in Morogoro and Shinyanga, Tanzania. Demographics, anthropometrics, dietary intakes and household food insecurity were recorded. ANCOVA was used to examine differences and interactions between farming systems, seasons, food security, and nutrition status. The results showed high food insecurity pre-harvest, highest within the Mixed Crop Livestock (MCL) farming system (82%) and Mixed Food Crop (MFC) farming system (74%). Post-harvest, food insecurity was lowest for MCL households (21%) and highest for Single Food Crop (SFC) households (49%). MFC infants and young children had lower WAZ and LAZ and Cash Crop (CC) infants and young children had higher WAZ and LAZ pre-harvest. Within the MFC and MCL farming systems, a significant increase pre to postharvest in MUAC was observed (p < 0.01 and p < 0.001, respectively). This study highlighted high food insecurity, poor dietary intakes and poor nutrition status pre-harvest. Our findings revealed that the CC farming system had a greater income-generating pathway and that MCL and MFC families had food group diversification post-harvest. Therefore, interventions to improve nutrition status should improve both farming systems, while addressing seasonal gaps through food storage and preservation, market access and nutrition education for better child nutrition.
