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 response surface methodology was used to study the conditions for a maximum recovery of phenolics from processing kiwi fruit residues. Ethanolic extracts were prepared with different conditions of pH (2, 5, 10), temperature (30, 50 and 70 ºC) and time (10, 20, 30 min). Total phenolics, total flavonoids content and antioxidant activities by 2,2-diphenyl-1-picrylhydrazyl scavenging capacity and ferric reducing antioxidant power were determined. Samples from optimal extraction condition were injected HPLC-DAD system to access the phenolic profile and content. The best extraction conditions were pH solvent of 2, 70 ºC of temperature and 20 min of extraction. Ten phenolics were identified: caffeic acid and its derivatives, chlorogenic acid and ferulic acid, (+)-catechin, (-)-epicatechin), rutin and quercitrin. These phenolics often reported as having important antioxidant, anti-inflammatory, antiaging and anticancer activities, turn this residues and excellent source of bioactive compounds to be used in agro-food, cosmetics or phytochemical industries.
