[Invariance of the Brazilian Food Insecurity Scale: analysis of demographic groups based on the Brazilian National Household Sample Survey].
Article in Cadernos de saude publica, 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
Population surveys have widely used the Brazilian Food Insecurity Scale (EBIA, acronym in Portuguese) to measure food insecurity in the country. Despite its well-established psychometric properties, few studies have evaluated its measurement invariance between territories, which is essential to ensure the validity of regional comparisons. This study investigated EBIA invariance regarding urban/rural areas, macro-regions, and Brazilian states based on data from the 2013 Brazilian National Household Sample Survey (PNAD, acronym in Portuguese). It analyzed the eight general/adult EBIA items by alignment in three independent partitions of the sample (116,543 households). The results indicated that the EBIA showed invariance between urban and rural areas and partial invariance between regions and between states. These findings reinforce the validity of the EBIA to monitor and compare food insecurity across Brazil.
