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

Algeria imports all of its enzymes for use in different fields, which causes a ‎serious economic problem as the cost of these enzymes is continuously rising. New enzymes with efficient and unique properties are always sought to meet the specific needs of various industry sectors. This study aimed to investigate the purification and characterization of α-amylase from the Algerian Geotrichum candidum PO27, and its potential application as a desizing agent in the textile industry. This enzyme was purified 6.73-fold in two process steps: concentration by ultrafiltration, followed by exclusion ‎chromatography, achieving a final recovery of 9.1%. The results showed that its molecular weight was estimated for the first time by SDS-‎PAGE as 19.2 kDa. Physicochemical characterization of purified enzyme revealed optimal activity at pH 5 and 70 °C, thermostability properties, and high stability in the presence of Mg
