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

Rett syndrome (RTT), caused by mutations in the methyl-CpG binding protein 2 gene (MECP2), is a debilitating autism spectrum developmental disorder predominantly affecting females. Mecp2 mutant mice have reduced levels of brain-derived neurotrophic factor (BDNF) in the brain; conditional deletion and overexpression of BDNF in the brain accelerates and slows, respectively, disease progression in Mecp2 mutant mice. Thus we tested the hypothesis that 7,8-dihydroxyflavone (7,8-DHF), a small molecule reported to activate the high affinity BDNF receptor (TrkB) in the CNS, would attenuate disease progression in Mecp2 mutant mice. Following weaning, 7,8-DHF was administered in drinking water throughout life. Treated mutant mice lived significantly longer compared with untreated mutant littermates (80 ± 4 and 66 ± 2 days, respectively). 7,8-DHF delayed body weight loss, increased neuronal nuclei size and enhanced voluntary locomotor (running wheel) distance in Mecp2 mutant mice. In addition, administration of 7,8-DHF partially improved breathing pattern irregularities and returned tidal volumes to near wild-type levels. Thus although the specific mechanisms are not completely known, 7,8-DHF appears to reduce disease symptoms in Mecp2 mutant mice and may have potential as a therapeutic treatment for RTT patients.
