Association Between Smoking and Amnesia in Southwest Iran: A Population-Based Cross-sectional Study.
Article in Journal of research in health sciences, 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
backgroundAmnesia is a cognitive impairment that manifests as a deficit in the retrieval of previous memories and the acquisition of novel information. Limited research, especially in Iran, exists on the risk factors of amnesia, and smoking might be linked to a greater likelihood of experiencing memory issues and cognitive decline, including amnesia. The aim of this study was to explore the risk factors associated with amnesia and the connection between smoking and amnesia.
methodsThis study was conducted at the baseline of the Hoveyzeh cohort study on adults aged 35-70 years in southwest Iran between 2016 and 2018. The required data on socioeconomic factors, demographic characteristics, history of stroke, history of epilepsy, and history of head trauma were collected from the participants. The relationship between smoking and amnesia was assessed, and multiple logistic regression was employed to account for potential confounding variables.
resultsThe mean age of the participants was 48.83±9.20 years, and 39% were male. The overall prevalence of amnesia was 4.2% (95% confidence interval [CI]: 3.8-4.6). The odds of having amnesia were significantly higher in smokers than in nonsmokers (adjusted odds ratio=1.52 [95% CI: 1.21-1.91]). Additionally, several other factors, including age, education level, type of residence, history of stroke, epilepsy, and history of trauma, were associated with amnesia.
conclusionOur investigations revealed a direct correlation between smoking and amnesia. To gain a more comprehensive understanding of the underlying mechanisms of these associations, it will be imperative to conduct future longitudinal studies.
