Oral Actinomyces isolates forming red colonies on brain heart blood agar can bee unambiguously classified as A odontolyticus by macroscopic examination.

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
The accurate classification of oral Actinomyces isolates as one species is difficult. Out of 18 Actinomyces isolates forming red colonies on brain heart blood agar, 12 could be straightforwardly assigned as Actinomyces odontolyticus by biochemical, morphological, and chemotaxonomic characteristics. For the remaining six isolates, the results of the different identification methods were inconsistent. By sequencing a 16S ribosomal DNA fragment by a rapid mass spectrometric method, all isolates could be identified unambiguously as A. odontolyticus. This result proves the importance of red colony pigmentation on brain heart blood agar together with the characteristic cell morphology for unequivocal assignment of oral Actinomyces isolates to the species A. odontolyticus.
