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

purposeWe aimed to investigate the clonal relationship and antifungal susceptibility of C. parapsilosis isolated from hospitalized patients and to determine whether it is due to transmission or not and the spread status of resistant isolates.

methodsBetween January 2017 and June 2019, totally 277 C parapsilosis isolated from blood, urine and catheter samples of adult or pediatric in-patient (intensive care and service) who applied to Mycology laboratory in our hospital were included in the study. All isolates were identified using conventional methods, API 20 C AUX (Biomerieux, France) semi-automated system and confirmed by MALDI-TOF MS Biotyper Smart (Bruker Daltonik GmbH, Germany). Randomly amplified polymorphic DNA (RAPD) PCR method was used for molecular genotyping of isolates. MIC values for fluconazole, anidulafungin and amphotericin B were determined according to the M27-A3 CLSI broth microdilution reference method guideline.

resultsSeven different band patterns (A-G) were detected in 277 isolates by RAPD PCR method. According to the rank order of the isolates, 170 (61.37%) C, 65 (23.47%) A, 18 (6.50%) G, 11 (3.97%) B, six (2.17%) E, two (0.72%) F and one (0.36%) D patterns were determined. When the band patterns of the isolates were evaluated according to the years, it was detected that C pattern continued between 2017 and 2019 and that all isolates continued to spread only as C pattern in 2019. While 211 (76.17%) of the isolates were resistant to fluconazole (≥ 8 µg/ml), two (0.72%) were resistant to amphotericin B (≥ 2 µg/ml) and two (0.72%) were intermediate to anidulafungin.

conclusionsIt is noteworthy that the spread of the C pattern in C. parapsilosis strains has increased over the years and is the main pattern isolated from the whole hospital. The detection of high fluconazole resistance in C. parapsilosis isolates in our hospital may also be related to the dominant pattern.
