Diagnostic accuracy of tru-cut biopsy and acid cytology from patients operated with suspicious for ovarian cancer*.

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
objectiveIn women who are believed to have ovarian cancer but have a poor performance status or have advanced disease thought to be beyond the scope of primary cytoreductive surgery, neoadjuvant chemotherapy can be administered with acid cytology and/or tru-cut biopsy referral. The aim of this study was to determine the accuracy, adequacy, safety, and reliability of these minimally invasive interventional procedures.
methodsThis is a retrospective analysis of 63 patients with a suspicion of ovarian cancer who reported to Bezmialem University Hospital between 2014 and 2021, underwent ultrasound-guided acid cytology and tru-cut biopsy, and also had postoperative final pathology results.
resultsOn comparing acid cytology and tru-cut biopsy at the same time with the postoperative final pathology results, it was seen that the positive predictive value was 100% in all groups. It was revealed that the sensitivity of acid cytology was 64%, the specificity was 100%, the negative predictive value was 12%, and the accuracy of the test was 65%. The sensitivity of the tru-cut biopsy was 91%, the specificity was 100%, the negative predictive value was 42%, and the accuracy of the test was 92%. In the case of both procedures, the sensitivity was calculated as 93% and the accuracy of the test was calculated as 93%. There were no false-positive cytology and biopsy results.
conclusionDue to its high reliability and accuracy, the combined application of these minimally invasive methods has the potential to routinely replace more invasive methods for adequate tumor sampling, such as diagnostic laparoscopy or exploratory laparotomy.
