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.
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
Three proteins, Egl330, Egl326 and Egl325, which covered the catalytic domain of a Bacillus subtilis endo-β-l, 4-glucanase were expressed in Escherichia coli and purified. Egl325 was a mutant of Egl330 with the peptide sequence Arg-Glu-Asn-Ile-Arg deleted in the C-terminus and Egl326 was another mutant of Egl330 with the peptide sequence Glu-Asn-Ile-Arg deleted in the C-terminus. These three proteins displayed same optimal reaction pH and temperature. However, the thermal stability and pH stability of Egl326 and Egl325 were diminished compared to Egl330. Results of ultra violet scanning, circular dichroism and Trp fluorescence spectrometry showed that the absence of the short peptide at the C-terminus of Egl330 resulted in the destabilization of the catalytic domain through affecting the folding of the protein.
