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

A selective enzymatic acetylation method for the protection of the second and the sixth positions of thio-d-galactopyranoside was found using immobilized Candida antarctica lipase-B (CAL-B). Unfortunately, it was determined that the immobilized enzyme cannot be recycled effectively. The optimized acetylation method was screened with different thioglycosides and with fully unprotected saccharides. New methods for several new partially protected saccharides were found, while the synthesis of some known saccharides, e.g., the third and the sixth position-protected d-glucose or the fourth position-protected l-rhamnose, was improved. Furthermore, an enzymatic acetal formation between the fourth and the sixth positions was discovered. The main limitation for acetylation reactions with CAL-B has been determined to be the substrate solubility.
