Nerve growth factor gene polymorphisms may be associated with heroin dependence in women but do not mediate specific personality traits.

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
Heroin dependence (HD) is a complex disease with a substantial genetic contribution and is associated with traits of impulsivity and specific personality traits. The neurotrophic factor nerve growth factor (NGF) may mediate the reward processes in HD. This study aims to investigate whether NGF gene polymorphisms are associated with the co-occurrence of HD and impulsivity/specific personality traits in HD patients. To minimize the potential confounding effects of population stratification, we selected a homogeneous Han Chinese population and recruited 1364 participants (831 HD patients and 533 healthy controls). In addition, 163 female HD patients completed the Chinese version of the Barratt Impulsiveness Scale Version 11 (BIS-11), and 440 HD patients completed the Chinese version of the Tridimensional Personality Questionnaire (TPQ) for subsequent analysis. We identified three polymorphisms with altered allele and genotype frequency in HD patients versus controls (p = 0.035 for rs2254527; p = 0.005 for rs6678788; p = 0.006 for rs7523654), especially in the female subgroup. Four associations identified via haplotype analysis were significant in the female subgroup (p = 0.003 for T-T-A haplotype and p = 0.002 for C-C-A haplotype in block 1; p = 0.011 for T-T haplotype and p = 0.009 for C-T haplotypes in block 2), but not in the male subgroup. Male HD patients had higher novelty-seeking (NS) scores, and female HD patients had higher harm avoidance (HA) scores. However, there was no significant association between the selected NGF polymorphisms and BIS or TPQ scores in HD patients. NGF variants may contribute to the risk of HD development in females but do not mediate the relationship between impulsivity and specific personality traits in the female population.
