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

Murtilla pomace (the by-product generated during juice production) shows a high phenolic content. Recovering phenolics from murtilla pomace is a sustainable approach towards zero waste. In this study, murtilla pomace was subjected to enzyme-assisted extraction using Viscozyme. The extracts were analyzed for TPC and phenolic profile. Antioxidant activity was evaluated by chemical-based assays and the antioxidant property was demonstrated for the first time in an ozone-induced oxidation process applied to a raw fish model system. Enzymatic pretreatment with Viscozyme increased the total phenolic content by up to 57%. The antioxidant activity also increased upon enzymatic treatment. The concentration of quercetin was positively affected, while the content of rutin decreased upon enzymatic pretreatment, likely reflecting the enzymatic hydrolysis biotransforming rutin glycoside into quercetin aglycone. Phenolics from murtilla pomace obtained upon enzyme-assisted extraction were shown to be effective as natural antioxidants against ozone-induced oxidation in salmon. Therefore, enzyme-assisted extraction may be an environmentally friendly strategy in the recovery of these natural antioxidants.
