Poverty and poor choices: socioeconomic gradients of unhealthy behaviors among adults in a multi-center cross-sectional study in Iran.
Article in BMC research notes, 2025. 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
objectiveWhile the association between socioeconomic status (SES) and mortality/morbidity is well-documented, the specific relationship between SES and unhealthy behaviors in countries like Iran remains understudied. Therefore, this study aims to examine the socioeconomic inequalities in the prevalence of seven unhealthy behaviors among 3,518 adults from nine provinces in Iran.
resultsSignificant socioeconomic status (SES)-related disparities were observed across multiple health behaviors. The poorest groups exhibited higher rates of physical inactivity (53.4% in the poorest vs. 41.2% in the richest; inequality ratio: 1.3), infrequent dental flossing (63.7% in the poorest vs. 30.1% in the richest; inequality ratio: 2.1), infrequent tooth brushing (27.4% in the poorest vs. 8.5% in the richest; inequality ratio: 3.2), poor sleep quality (27.2% in the poorest vs. 9.7% in the richest; inequality ratio: 2.8), and breakfast skipping (58.2% in the poorest vs. 47.6% in the richest). Conversely, alcohol consumption was more prevalent among the richest group (22.5% in the richest vs. 10.7% in the poorest; inequality ratio: 0.5). Current smoking rates were 26.5% for the poorest and 21.2% for the richest. Concentration index analysis revealed pro-poor gradients for all unhealthy behaviors except alcohol consumption (CI = 0.1041, p < 0.001), with notable pro-poor gradients observed for physical inactivity (CI= -0.0586, p = 0.002), poor sleep quality (CI= -0.1997, p < 0.001) and tooth brushing (CI= -0.2542, p < 0.001). The sex-stratified analysis revealed distinct socioeconomic patterns: physical inactivity exhibited stronger pro-poor gradients in males (CI= -0.0701) compared to females (CI= -0.0483).
