Performance of a New Brazilian Self-Sampling Device for High-Risk Human Papillomavirus Screening.

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 evaluate the performance of a new Brazilian self-sampling device (COARI®) compared with clinician-collected samples for high-risk human papillomavirus (hrHPV) detection and partial typing.
methodsThis diagnostic agreement study included 57 women who underwent routine cervical screening or follow-up at a private health center in Maringá, Brazil, between May and October 2023. Each participant provided two samples: a self-collected vaginal sample using the COARI® device (Kolplast, Brazil) and a clinician-collected cervical sample. Both were tested using the Cobas® HPV 4800 assay (Roche, USA), which detects HPV16, HPV18, and a pooled group of 12 other hrHPV types.
resultshrHPV detection was significantly higher in self-collected samples than in clinician-collected ones (52.9% vs. 37.2%; P = 0.008). The Overall agreement between sampling methods was 84.3%. All discordant cases (15.7%) were hrHPV-positive in self-collected samples and negative in clinician-collected specimens, suggesting potentially greater sensitivity for self-sampling. The COARI® device showed 100% sensitivity and a 100% negative predictive value, with an overall accuracy of 84.3%.
conclusionThe COARI® self-sampling device demonstrated reliable and effective performance for hrHPV detection and partial typing, showing strong potential to increase access to and coverage of cervical cancer screening in Brazil. Further studies with larger and more diverse populations are needed to validate these findings and inform public health implementation.
