Development and validation of a food retail environment analysis protocol in Iran.
Article in Public health nutrition, 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
objectiveThis study aimed to adapt and validate a Food Retail Environment Analysis Protocol in Shiraz, Iran.
designThe protocol was developed by integrating the Nutrition Environment Measurement Survey in Stores with the food retail module from the International Network for Food and Obesity/Non-communicable Diseases Research, Monitoring, and Action Support. After translating, synthesising and back-translating the protocol, a panel of experts reviewed and refined it to ensure cultural and contextual appropriateness. Its validity was assessed through expert evaluation, and the pre-final version was field-tested to assess reliability across different food retail environments.
settingShiraz City, a metropolis in Iran.
participantsNine food retail stores, including kiosks, small- and medium-sized food retailers (comparable to convenience stores) and large food retailers (comparable to grocery stores).
resultsContent and face validity were assessed using the content validity ratio (0·64-1), content validity index (0·78-1) and item impact score (2·84-4·83). Reliability testing by two researchers showed a 93·77 % agreement and an intraclass correlation coefficient of 0·89-1. The protocol includes fourteen food groups, most of which are categorised as either healthy or unhealthy. It evaluates product availability, prominence, quality, pricing and both in-store and out-of-store food promotions.
conclusionThe validated protocol effectively assesses diverse retail food environments, offering essential data for evaluating policies and guiding interventions to improve healthy food access. It is adaptable for broader regional or international application in public health and food policy contexts.
