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

An endochitinase gene from the Serratia marcescens Nima strain (chiA Nima) was cloned, sequenced, and expressed in Escherichia coli DH5alphaF', and the recombinant protein (ChiA Nima) was purified by hydrophobic interaction chromatography. chiA Nima contains an open reading frame (ORF) that encodes an endochitinase with a deduced molecular weight and an isoelectric point of 61 kDa and 6.84, respectively. A sequence at the 5'-end was identified as a signal peptide, recognized by Gram-negative bacteria transport mechanism. Comparison of ChiA Nima with other chitinases revealed a modular structure formed by the catalytic domain and a putative chitin-binding domain. The purified chitinase was able to hydrolyze both trimeric and tetrameric fluorogenic substrates, but not a chitobiose analog substrate. ChiA Nima showed high enzymatic activity within a broad pH range (pH 4.0-10.0), with a peak activity at pH 5.5. The optimal temperature for enzymatic activity was detected at 55 degrees C.
