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

Substantial evidence exists to support the hypothesis that high fruit and vegetable consumption, rich in antioxidants, can reduce the incidence of several disease states. The aim of this study was to compare the results obtained by six spectrophotometric biochemical methods including the ferric reducing antioxidant power (FRAP), 2, 2-diphenyl-1-picryhydrazyl (DPPH•), 2,2-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS•⁺), copper (II) reducing capacity (CUPRAC) and Cerium (IV) reducing antioxidant capacity (CERAC) assays as well as Folin-Ciocalteu method (FC) for the measurement of total antioxidant capacity (TAC) and total polyphenols (TP) in different commercially available vegetable juices. There was a significant positive correlation between the results obtained for FRAP, ABTS•⁺, CUPRAC, CERAC and FC (0.68 ≤ r ≤ 0.96, P < 0.01). DPPH• was only correlated with CERAC (r = 0.66, P < 0.01). Beetroot juice had the highest TAC and TP regardless of the method of analysis.
