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

Telomere-linked RecQ helicase (TLH) genes have been identified in several fungi, where they occur as small gene families with each member copy residing within ~10 kb of a telomere. Here we describe the characterization of all 11 TLH gene copies in the reference strain of the fungus Magnaporthe oryzae. A consensus gene prediction revealed that the previously reported TLH1 gene is actually a mutated copy, and the full-length gene is almost two times longer. Only four full-length TLH genes were present in the strain that was analyzed, with the remaining copies containing premature stops caused by point mutations, indels, transposon insertions, and a telomere truncation. Interestingly, all of the TLH gene copies possessed numerous mutations indicative of the action of the repeat-induced point mutation process. However, there was evidence of purifying selection indicating maintenance of gene function. Alignment of full-length proteins from M. oryzae, Schizosaccharomyces pombe and M. anisopliae revealed the presence of a novel, highly conserved protein motif which suggests that the telomere-linked helicases have different functions and/or substrates to the RecQ helicases encoded by "internal" genes.
