Distinguishing Candida species by beta-N-acetylhexosaminidase activity.
Article in Journal of clinical microbiology, 2001. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
A variety of fungi produce the hydrolytic enzyme beta-N-acetylhexosaminidase (HexNAcase), which can be readily detected in assays by using p-nitrophenyl-N-acetyl-beta-D-glucosaminide as a substrate. In the present study we developed a microtiter plate-based HexNAcase assay for distinguishing Candida albicans and Candida dubliniensis strains from other yeast species. HexNAcase activity was detected in 89 of 92 (97%) C. albicans strains and 4 of 4 C. dubliniensis strains but not in 28 strains of eight other Candida species, 4 Saccharomyces cerevisiae strains, or 2 Cryptococcus neoformans strains. The HexNAcase activity in C. albicans and C. dubliniensis was strain specific. All except three clinical C. albicans isolates among the C. albicans strains tested produced enzyme activity within 24 h. These strains did produce enzyme activity, however, after a prolonged incubation period. For two of these atypical strains, genomic DNA at the C. albicans HEX1 gene locus, which encodes HexNAcase, showed nucleotide differences from the sequence of control strains. Among the other Candida species tested, only C. dubliniensis had a DNA sequence that hybridized with the HEX1 probe under low-stringency conditions. The microtiter plate-based assay used in the present study for the detection of HexNAcase activity is a simple, relatively inexpensive method useful for the presumptive identification of C. albicans and C. dubliniensis.
