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

We report a mutation of UBE2A/HR6A, which encodes a ubiquitin-conjugating enzyme (E2), a member of the ubiquitin proteasome pathway, as the cause of a novel X-linked mental retardation (XLMR) syndrome that affects three males in a two-generation family. A single-nucleotide substitution, c.382C-->T in UBE2A, led to a premature UAG stop codon (Q128X). As a consequence, the predicted polypeptide lacks the 25 C-terminal amino acid residues. The importance of this terminal sequence for UBE2 function is inferred by its conservation in vertebrates and in Drosophila. UBE2A mutations do not appear to significantly contribute to XLMR, since no UBE2A mutations were identified in 15 families with nonsyndromic and 4 families with syndromic idiopathic XLMR previously mapped to intervals encompassing this gene. This is the first description of a mutation in a ubiquitin-conjugating enzyme gene as the cause of a human disease.
