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

backgroundThere is emerging evidence that clinical and neuro-pathological manifestations of Huntington's disease (HD) may occur in individuals with intermediate length cytosine-adenine-guanine (CAG) repeats (27-35 CAG repeats) in the Huntingtin (HTT) gene. We aim to further define the clinical characteristics of individuals who possess CAG repeat lengths in this range.

methodsData from the Cooperative Huntington's Observational Research Trial (COHORT) were analyzed. Participants were categorized according to the number of CAG repeats into normal (≤26), intermediate (27-35) and HD (≥36) groups. The motor, cognitive and behavioral scores on the Unified Huntington's Disease Rating Scale (UHDRS) were compared between the intermediate and normal groups.

resultsOf 1985 individuals affected by HD or with a family history of HD who were genotyped, 50 (2.5%) had their larger CAG repeat in the intermediate range. There were statistically significant differences in scores of some motor, cognitive, and behavioral domains of UHDRS at baseline between normal and intermediate length CAG repeats. Furthermore, a significantly greater number of subjects with CAG repeats in the intermediate range reported at least one suicide attempt compared to the normal group. DISCUSSION: Our findings of motor, cognitive and behavioral abnormalities in individuals with intermediate CAG repeats suggest the presence of subtle, but relevant, disease manifestations in patients with intermediate CAG repeats. These results have important implications for the pathogenesis of the disease and genetic counseling.
