Interaction Between the 5-Hydroxytryptamine Transporter-Linked Polymorphic Region (5-HTTLPR) and Negative Life Events in Adolescent Heavy Drinking.

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
objectiveThis study investigates whether the reciprocal associations between negative life events and drinking over time differ as a function of 5-HTTLPR (5-hydroxytryptamine [serotonin] transporter-linked polymorphic region) genotype (i.e., candidate gene and environment interaction and correlation) using large and population-based prospective data from adolescents.
methodA total of 4,916 White adolescents in the United Kingdom (mean ages = 16, 17, and 18 years old over three assessment points; 47% female) were used. Tri-allelic 5-HTTLPR genotype was assessed; negative life events were assessed at ages 16 and 17; and frequency of heavy drinking was assessed at ages 16, 17, and 18. Path analyses after controlling for covariate interactions and multigroup cross-lagged analyses were conducted.
resultsThe null findings of candidate gene and environment interaction and correlation were found in the path analyses controlling for covariate interactions, and they were replicated in the multigroup cross-lagged analyses. No moderation by 5-HTTLPR in the association of negative life events at age 16 with heavy drinking at age 17 as well as no association of negative life events at age 17 with heavy drinking at age 18 were found. Also, the 5-HTTLPR genotype did not moderate the association of heavy drinking at age 16 with negative life events at age 17.
conclusionsUsing large prospective data, it appears that there is no evidence for 5-HTTLPR-moderated drinking following experience of negative life events and no support for 5-HTTLPR-moderated selection to negative life events among mid/late adolescents. This finding may inform developmental patterns in gene and environment interaction effects by showing that the effects are less pronounced in mid/late adolescence than in early adolescence.
