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

In 1935, Shiro Akabori began research on the preparation of taka-amylase A with a purity suitable for chemical research, with the intention of elucidating the chemical nature of the enzyme. He succeeded in developing a method to efficiently obtain crystallized taka-amylase A from Aspergillus oryzae. Using crystallized taka-amylase A as the starting material, a series of studies were conducted to determine its amino acid composition and sequence, sugar chain structure, and three-dimensional structure. Based on these results, the molecular structure and catalytic mechanism of taka-amylase A were elucidated. The scientific achievements from research on taka-amylase A significantly enhanced Japan's capabilities in protein research, represented by the fact that taka-amylase A was the first amylase in the world for which both chemical and crystallographic structures were elucidated.
