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
Hydrophobic interactions, based on cell surface hydrophobicity (CSH), are among the many and varied mechanisms of adherence deployed by the pathogenic yeast Candida albicans. Recently it was shown that, unlike C. albicans, C. dubliniensis is a species that exhibits an outer fibrillar layer consistent with constant CSH. Previously, C. dubliniensis grown at 25 or 37 degrees C was shown to coaggregate with the oral anaerobic bacterium Fusobacterium nucleatum. C. albicans, however, demonstrated similar coaggregation only when hydrophobic or grown at 25 degrees C. This observation implied that coaggregation of Candida cells with F. nucleatum is associated with a hydrophobic yeast cell surface. To test this hypothesis, 42 C. albicans and 40 C. dubliniensis clinical isolates, including a C. albicans hydrophobic variant, were grown at 25 and 37 degrees C and tested with the established hydrophobicity microsphere assay, which determines CSH levels based on the number of microspheres attached to the yeast cells. The coaggregation assay was performed in parallel experiments. All C. dubliniensis isolates grown at either temperature, hydrophobic 25 degrees C-grown C. albicans isolates, and the C. albicans hydrophobic variant, unlike the 37 degrees C-hydrophilic C. albicans isolates, exhibited hydrophobic CSH levels with the microsphere assay and simultaneously showed maximum, 4+, coaggregation with F. nucleatum. The parallel results obtained for C. dubliniensis using both assays support the use of the CoAg assay both as a rapid assay to determine CSH and to differentiate between C. dubliniensis and C. albicans.
