Identification of Campylobacter fetus subspecies by phenotypic differentiation and PCR.
Article in Journal of clinical microbiology, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 papers.
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 species Campylobacter fetus is divided into the subspecies C. fetus subsp. venerealis and C. fetus subsp. fetus, which differ in their epidemiologies and clinical importance. The differences between these subspecies make accurate distinction between the two essential. First, the value of seven key tests for the traditional differentiation of C. fetus was investigated. Afterwards, the results of the phenotypic differentiation and PCR were compared to address the question of the reliability of this PCR assay. Altogether, 103 C. fetus isolates were investigated, including the type strains of C. fetus subsp. fetus and C. fetus subsp. venerealis. Depending on the result of the glycine tolerance test, the isolates could be separated into 81 C. fetus subsp. venerealis isolates (glycine intolerant) and 22 C. fetus subsp. fetus isolates (glycine tolerant). For all C. fetus subsp. venerealis strains tested, the results of the selenite reduction assay and sensitivity to metronidazole and cefoperazone completely agreed with the results of the glycine tolerance test (correspondence, 100%). Seventy-three C. fetus subsp. venerealis isolates did not grow at 42 degrees C (correspondence, 90.1%), but eight isolates showed a faintly discernible, flat, dark gray growth. For 22 C. fetus subsp. fetus isolates, the results of additional phenotypic tests only partly agreed with the results of the glycine tolerance test. For C. fetus subsp. fetus the results of the glycine tolerance test showed a relatively good correspondence with those of the selenite reduction assay (correspondence, 81.8%), assays for cefoperazone resistance (correspondence, 86.4%), and assays for growth at 42 degrees C (correspondence, 81.8%). The results of the glycine tolerance test and PCR completely agreed for the 103 C. fetus isolates tested. We conclude that at present the traditional phenotypic characterization of C. fetus subspecies under strongly defined conditions remains indispensable, but this PCR assay constitutes a valuable adjunctive technique for the confirmation of phenotypic results.
