Investigation of Atypical Cell Parameter in the Surveillance of Patients with NMIBC; Initial Outcomes of a Single Center Prospective Study.

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
objectiveTo investigate how well the Sysmex automated urine-analyzer's atypical-cell parameter can predict oncological outcomes when compared to cytology and pathology data in the follow-up of NMIBC patients. MATERIAL AND
methodsWe prospectively collected clinical data from 273 patients who underwent cystoscopic examination due to benign and malign reasons in our center between June 2020 and March 2021. Patients were divided into 2 groups. (Group-1: Patients with no previous diagnosis of bladder cancer(BC), Group-2: Patients with previously diagnosed NMIBC). The a typical-cell parameter was determined by studying the urine sample given by the patient for urinalysis. The atypical-cell parameter's sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) were assessed.
resultsA total of 76(41.1%) patients underwent diagnostic procedures (Group-1) and remaining 109(58.9%) patients were NMIBC patients (Group-2) who subjected to control cystoscopy on follow-up. BC was detected in 70 patients, 28 of whom were newly diagnosed (Group-1). Remaining 42 patients had recurrence during their follow-up (Group-2). Atypical cell values of 70 patients with BC were determined to be statistically significantly higher than those without malignancy. In Group-2, median atypical-cell values for those with no malignancy, those with low-grade BC reccurrence, and those with high-grade BC recurrence were 0.00(IQR:0.00-0.80), 0.25(IQR:0.10℃1.10) and 1.20(IQR:0.70-2.15), respectively (p<0.001). For a cut-off of 0.1 atypical cells/µL, sensitivity and specificity were measured as 83.33% and 53.73%, respectivel (AUC:0.727;p-value<0.001).
conclusionAtypical-cell parameter of the Sysmex-UF-5000 automated urine-analyzer is a newly introduced research parameter. The results of this study are promising. Based on our results, we presume that the atypical-cell parameter may be used in surveillance of the NMIBC patients. Multi-center studies with larger patient populations are required to prove its efficacy.
