Diagnostic accuracy of intraoperative haptoglobin point-of-care testing in ovarian tumor fluid versus frozen section for epithelial ovarian cancer.
Article in BMC research notes, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveOvarian cancer is the third most common gynaecological cancer and has the high mortality rates and requires accurate intraoperative. Haptoglobin is an acute-phase protein locally elevated in cancer cells, may serve as a novel diagnostic marker. This study aimed to evaluate the diagnostic accuracy of a haptoglobin point-of-care test using intraoperatively aspirated ovarian cyst fluid for detecting epithelial ovarian carcinoma.
resultA total of 55 patients with suspected malignant ovarian tumors were enrolled, with 11 excluded, resulting in 44 patients for analysis. Frozen sections were found to have a diagnostic accuracy of 100% compared with histopathology, whereas haptoglobin had an accuracy of 90.91%. The sensitivity, specificity, PPV, and NPV of the haptoglobin test were 90.48, 91.3, 90.49, and 91.3%, respectively. Haptoglobin testing in ovarian cyst fluid demonstrates promising diagnostic performance and may serve as a complementary tool alongside established intraoperative methods.
