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

The Transcription Factor Activating Protein-2β (TFAP-2β) gene has been shown to influence monoaminergic neurotransmission, and several genes important for monoaminergic function have binding sites for TFAP-2β. Familial studies of attention deficit hyperactivity disorder (ADHD) suggest a hereditary-determined subtype of ADHD with comorbid depression. We examined a functional variation of the TFAP-2β gene in the context of co-occurring symptoms of ADHD and depression in two independent population-based samples of adolescents (Group A, n = 175 and Group B, n = 1,506) from Sweden. Results indicated 6.1 to 7.8% of adolescents screened positively for ADHD and depression symptoms. Symptoms of depression were more common among girls who screened positively for ADHD and did not carry the nine-repeat allele of the TFAP-2β intron 1 Variable Number Tandem Repeat (VNTR) polymorphism. The presence of the nine-repeat variant of the TFAP-2β intron 1 VNTR appears to protect girls with ADHD symptoms from the co-expression of symptoms of depression.
