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

objectiveThe aim of this study was to evaluate the accuracy of detecting malignancies by directly sampled endometrial cytology using globally adopted ThinPrep with a novel preparation technique.

methodsMedical records and reports of pathology and cytology from June 2019 to March 2022 were reviewed. We selected 112 endometrial cytology specimens using ThinPrep with the novel preparation technique, where the clinical course or pathological samples confirmed negative or positive results. Eight cytotechnologists or cytopathologists examined the cytology specimens and provided reports based on standardised criteria from the descriptive reporting system for endometrial cytology (the Yokohama System).

resultsThe 112 specimens were evenly smeared and well prepared, featuring high quality, with no issues hindering microscopic examination. Examiners unfamiliar with endometrial cytology using ThinPrep showed high diagnostic accuracy, demonstrating that this modality of preparation for endometrial cytology is feasible for clinical use.

conclusionsThe novel preparation method using ThinPrep successfully provided high-quality, standardised specimens. Furthermore, employing the Yokohama System enabled high accuracy in detecting endometrial malignancies, even for examiners with minimal experience with this cytological technique. This suggests that ThinPrep-based endometrial cytology can be globally adopted with ease, potentially contributing significantly to the early detection of endometrial cancer.
