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

backgroundOur group previously reported on the high bactericidal potential of berry juices, particularly those derived from blackcurrant fruits. In the present study, we tested the efficiency of various juice fractions from blackcurrant fruits (all-fruit juice: AFJ, squeezed juice: SJ, non-dialyzable juice material: NDFM, alcoholic fraction from berry skins: AFBS, aqueous fraction from berry skins: AQFBS) in their efficiency to suppress various oral gram-positive and gram-negative bacteria.

methodsAFJ, SJ, NDFM, AFBS, and AQFBS were prepared from freshly harvested blackcurrant fruits. These fractions were used for direct contact tests with planktonic cultures of Fusobacterium nucleatum (F.n.), Aggregatibacter actinomycetemcomitans (A.a.), Porphyromonas gingivalis (P.g.), Streptococcus gordonii (S.g.), Streptococcus mutans (S.m.), Streptococcus sobrinus (S.s.), Actinomyces naeslundii (A.n.), and Enterococcus faecalis (E.f.).

resultsAFJ was the most efficient fraction, causing complete suppression of F.n., P.g., and S.g., and inducing a major reduction in A.a., A.n., and E.f. colony count. Bactericidal efficiency of the juices presents as follows: AFJ> AFBS > SJ> AQFBS> NDFM. Gram-negative bacteria were more susceptible to blackcurrant extracts compared to gram-positive species. AFJ efficiency was similar to 0.2% chlorhexidine solution in suppressing F. n., P. g., and S. g.

conclusionsAll-fruit juice from blackcurrant shows a strong bactericidal activity on F.n., A.a., P.g., S.g., and A.n. Further research should investigate the potential of blackcurrant fruit extracts in controlling oral biofilm formation.
