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

Fungal cell walls consist of various glucans and chitin. An inky cap, Coprinellus congregates, produced mushrooms at 25 degrees C in a regime of 15 h light/9 h dark, and then the mushroom was autolyzed rapidly to generate black liquid droplets where no cell wall was detected by microscopy. A chitinase cDNA from the matured mushroom cells of C. congregates that consisted of 1,541 nucleotides was successfully cloned using the rapid amplification of cDNA ends (RACE)-PCR technique. Its deduced 441 amino acid sequence had the conserved catalytic domain as in other fungal chitinase family 18. Chitinase activity was higher at the matured mushroom stage than primordial and young mushroom stage. When the expression of the cloned chitinase was examined by real-time PCR using the chitinase-specific primers, it was increased more than twice to 20 times during the autolytic process of mushroom than young mushroom or primordial stages, respectively.
