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

Several evidences suggested that the serotonin 5-HT1B receptor gene (HRT1B) might be involved in the susceptibility to attention deficit/hyperactivity disorder (ADHD). Prior studies reported excess transmissions of the HRT1B gene 861G allele to affected ADHD children and of a haplotype block containing this variant and two functional promoter SNPs to probands with ADHD-inattentive subtype. However, some investigations did not replicate these findings. Therefore, we tested for biased transmissions of haplotypes derived from the 861G > C, -161A > T, and -261T > G SNPs from parents to 343 families with ADHD children. We also sought to replicate findings from the literature that the association between HTR1B is preferentially with ADHD-Inattentive subtype. Using a transmission disequilibrium test we found evidence for an excess transmission of haplotype. -261G/-161T/861G (P = 0.014) for affected children in the total sample. When the analysis was repeated with 143 families with ADHD-Inattentive subtype no significant associations were observed. Our results provide additional evidence that HRT1B gene may be an important risk factor for the development of ADHD, but this effect seems not to be attributable to inattentive cases.
