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: To investigate the predictive value of preoperative serum thyroglobulin (Tg) and anti-thyroglobulin antibodies (TgAb) for central compartment lymph node metastasis (CLNM) in patients with clinically node-negative (cN0) papillary thyroid carcinoma (PTC). Methods: A retrospective analysis was conducted on clinical data from patients with cN0 PTC who underwent total thyroidectomy with central compartment lymph node dissection at our hospital between January 2018 and December 2023. Patients were randomly divided into a training cohort and a validation cohort in a 7:3 ratio. Data collected included patient demographics, clinicopathological characteristics, and preoperative serum Tg and TgAb levels. The outcome measure was pathologically confirmed CLNM status. Univariate and multivariate logistic regression analyses were employed to identify independent predictors of CLNM. The predictive value of preoperative serum Tg, TgAb, and the constructed prediction model for CLNM was assessed using receiver operating characteristic (ROC) curve analysis. Results: A total of 790 patients were enrolled in this study, comprising 553 in the training cohort and 237 in the validation cohort. The overall incidence of CLNM was 37.7% (298/790). In the training cohort, preoperative serum Tg and TgAb levels were significantly higher in the CLNM group compared to the non-CLNM group ( Conclusion: Preoperative serum Tg and TgAb are independent predictors of CLNM in cN0 PTC patients. The prediction model, which combined these serological markers with clinicopathological characteristics demonstrates good predictive performance and may offer valuable guidance for clinical decision-making regarding the necessity of prophylactic central compartment lymph node dissection in cN0 PTC patients.
