Are processed fruits and vegetables able to reduce diet costs and address micronutrient deficiencies? Evidence from rural Tanzania.
Article in Public health nutrition, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo assess the impact of integrating processed fruits and vegetables (FV) into diets in terms of diet cost reduction and ensuring nutritional adequacy year-round.
designMarket surveys were conducted to record foods. Focus group discussions (FGD) and 24-h dietary assessments - from children and women - were carried out to determine culturally accepted dietary habits. Six processed FV were considered for addition to diets. Using the Cost of Diet linear programming tool, standards diets were first modelled, and subsequently, the processed FV were included to analyse their impact.
settingRural Tanzania: Mtwara and Morogoro.
participantsMarket survey: 50 traders; FGD: 40 women; 24-h recalls: 36 infants aged 6-23 months, 52 children aged 6-13 years and 292 women.
resultsThe standard diet costs between TZS 232 and 2368 (USD 0·3-3) daily for infants. For children aged 6-13 years, it costs between TZS 1711 and 7199 (USD 2·2-9·1) daily and the cost for the women was between TZS 2793 and 10 449 (USD 3·5-13·2). Addition of the processed FV reduced diet costs by up to 61 %, 48 % and 49 % for children aged 12-23 months, children aged 6-13 years and women, respectively. However, for infants aged 6-11 months, costs rose by up to 127 %. The processed FV addressed all micronutrient gaps in the diets except for infants aged 6-11 months, where some micronutrient intakes were unfulfilled.
conclusionsProcessed FV could provide a feasible option to ensure availability of nutritious but cheap diets year-round. Hence, interventions to process FV into nutritious and affordable products should extensively be pursued.
