Assessing the association between ADH5 and ALDH1A1 genetic variants and substance use disorder risk in a Jordanian male population.
Article in BMC genomics, 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
backgroundSubstance Use Disorder (SUD) is a severe global problem that is influenced by both environmental and genetic factors. The genetic etiology of addiction can be complex and overlapping. This study aimed to investigate the association between two genes, ADH5 and ALDH1A1, and drug addiction in Jordanian males.
methodsThis study included 496 addicted patients and 496 healthy controls of Arab descent. The addicted participants were identified as Jordanian males with dependence on substances such as amphetamines, synthetic cannabinoids, benzodiazepines, alcohol, opiates, cocaine, and multiple substances. The participants' DNA was extracted, and 20 selected SNPs within ADH5 and ALDH1A1 were genotyped using the MassARRAY™ system. The statistical analysis was carried out using SPSS.
resultsThe study investigated associations between 20 variants within the ADH5 and ALDH1A1 genes and substance use disorder in Jordanian males. No statistically significant association was observed between individual polymorphisms and addiction (P > 0.05). However, the haplotypes CCGTTTTGTTTGG and CCCTTGTGTTCGG within the ALDH1A1 gene were significantly associated with an increased risk of addiction, with P-values of 0.0022 and 0.049 and odds ratios (OR) of 2.34 and 1.91, respectively.
conclusionThis study did not find a significant association between ADH5 and ALDH1A1 gene polymorphisms with addiction in Jordanian males. The authors suggest replicating this type of study with larger sample sizes and more variants in the same or different genes to confirm their findings.
