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

The Trichoderma reesei xln2 gene coding for the pI9.0 endoxylanase was isolated from the wild-type strain QM6a. The gene contains one intron of 108 nucleotides and codes for a protein of 223 amino acids in which two putative N-glycosylation target sites were found. Three different T. reesei strains were transformed by targeting a construct composed of the xln2 gene, including its promoter, to the endogenous cbh1 locus. Highest overall production levels of xylanase were obtained using T. reesei ALKO2721, a genetically engineered strain, as a host. Integration into the cbh1 locus was not required for enhanced expression under control of the xln2 promoter.
