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

GM2 gangliosidosis AB variant (GM2AB) is a rare neurodegenerative lysosomal storage disorder with clinical features resembling Tay-Sachs disease but characterized by normal lysosomal β-hexosaminidase A enzyme activity. To date, only 14 cases of the acute infantile form have been reported. To the best of our knowledge, this is the first case of GM2AB in a Portuguese patient reported in the literature. We describe the case of a girl with GM2AB, whose clinical presentation and pathological findings were critical for diagnosis. Post-mortem genetic sequencing identified a pathogenic mutation in homozygosity in the
