Characterization and stabilization of the α-L-fucosidase set from Lacticaseibacillus rhamnosus INIA P603.

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.
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
This study describes the molecular identification, biochemical characterization, and stabilization of three recombinant AlfA, AlfB, and AlfC fucosidases from Lacticaseibacillus rhamnosus INIA P603. Even though previous studies revealed the presence of fucosidase activity in L. rhamnosus extracts, the identification of the fucosidases, their physicochemical properties, and the substrate spectrum remained unknown. Although the presence of alfB is not common in strains of L. rhamnosus, fucosidases from L. rhamnosus INIA P603 were selected because this strain exhibited higher fucosidase activity in culture and the complete set of fucosidases. A high yield of purified recombinant AlfA, AlfB, and AlfC fucosidases was obtained (8, 12, and 18 mg, respectively). AlfA, AlfB, and AlfC showed their optimal activities at pH 5.0 and 4.0 at 60 °C, 40 °C, and 50 °C, respectively. Unlike 3-fucosyllactose, all three recombinant fucosidases were able to hydrolyze 2'-fucosyllactose (2'-FL), and their activities were improved through their immobilization on agarose supports. Nevertheless, immobilized AlfB exhibited the highest hydrolysis, releasing 39.6 µmol of fucose mg enzyme
