Diagnostic value of preoperative hemogram parameters in patients with papillary thyroid cancer: An age- and sex-matched retrospective 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
Objective: The aim of this study was to evaluate the diagnostic value of preoperative hemogram parameters —platelet count (PLT), plateletcrit (PCT), platelet distribution width (PDW), mean platelet volume (MPV), and red cell distribution width (RDW)— in differentiating papillary thyroid carcinoma (PTC) from benign thyroid pathology in an age- and sex-matched patient series. Material and Methods: A total of 2.080 patients who underwent total thyroidectomy at the Gazi University Faculty of Medicine, Department of General Surgery between January 2015 and January 2023 were retrospectively reviewed. After applying exclusion criteria and removing outliers, 1.955 patients were identified. Cases with a histopathological diagnosis of PTC were matched 1:1 with patients with benign thyroid pathology based on sex and 10-year age groups. The final analysis included 348 PTC patients and 348 benign patients (n=696). Preoperative hemogram parameters were compared between the groups using the Mann-Whitney U test, and the diagnostic value was assessed using receiver operating characteristic (ROC) curve analysis. Results: After matching, no significant difference was found between groups in terms of age (48.0±12.7 vs. 48.3±12.9 years; p=0.754) or sex distribution (p=0.930). None of the parameters —PLT (277.0±70.4 vs. 275.7±69.1 ×10 Conclusion: When age- and sex-matching are applied, preoperative PLT, PCT, PDW, MPV, and RDW values do not provide meaningful discrimination between PTC and benign thyroid pathology. Positive findings reported in the literature may be partly attributable to demographic confounding. The potential diagnostic value of combined indices or integration with other complete blood count parameters warrants investigation in prospective studies.
