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

Previous studies have shown that expansion-prone repeats form structures that inhibit human flap endonuclease (FEN-1). We report here that faulty processing by FEN-1 initiates repeat instability in mammalian cells. Disease-length CAG tracts in Huntington's disease mice heterozygous for FEN-1 display a tendency toward expansions over contractions during intergenerational inheritance compared to those in homozygous wild-type mice. Further, with regard to human cells expressing a nuclease-defective FEN-1, we provide direct evidence that an unprocessed FEN-1 substrate is a precursor to instability. In cells with no endogenous defects in DNA repair, exogenous nuclease-defective FEN-1 causes repeat instability and aberrant DNA repair. Inefficient flap processing blocks the formation of Rad51/BRCA1 complexes but invokes repair by other pathways.
