Changes in household food purchases in Iran: income and urban-rural inequality.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRegular monitoring of nutritional indicators serves as an early warning system for policymakers and is essential for the effective governance of food security. This study presents the first 18-year trend analysis of changes in Iranian household food purchases, with a specific focus on inequalities across income deciles and between urban and rural areas in Iran.
methodsData from the Statistical Center of Iran (2005-2022) were analyzed. Six major food groups, calories, and macronutrients derived from household purchases were examined. Linear regression, with year as a continuous predictor, was performed using SPSS (p < 0.05 considered significant). Data processing and figure generation were conducted using Microsoft Access 2016 and Excel 2016, respectively.
resultsOver the 18-year study period, per capita purchases of all major food groups declined in both urban and rural areas. Urban-rural disparities in household food purchases, as well as the associated estimated calorie and macronutrient quantities, narrowed. Furthermore, although higher-income households consistently purchased more of most food groups (except cereals) than lower-income households, these income-based inequalities also diminished over time.
conclusionAlthough nutritional inequalities in Iran have decreased in recent years, the simultaneous decline in overall household food purchases calls for more rigorous research on the subject. Analyzing long-term trends in household food purchase-based nutritional indicators is a critical scientific and policy priority for evaluating programs and designing evidence-based policies.
