1 · What the graph read from it

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.

2 · The registry

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

Previous studies robustly link childhood peer victimization experience to the timing of substance use initiation. However, no study has investigated the contributions of genetic and environmental factors to this link. The current study focused on a sample of 779 twin pairs followed from age 9-10 to 19-20, which is racially/ethnically and socioeconomically representative of the greater Los Angeles area. The aims were to investigate (1) the associations between childhood victimization, including physical (e.g., kicking, pushing), verbal (e.g., taunting), and relational victimization (e.g., spreading rumors), and timing of substance use initiation, and (2) the contributions of genetic/environmental factors to these associations. Multinomial logistic regressions revealed several small associations, but none of these survived corrections for multiple testing. Univariate genetic models suggested genetic (A) and nonshared environmental influences (E) on verbal victimization (V
