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
purposeUltrasonography (US) is the most accurate and cost-effective imaging method for identifying thyroid nodules. The difficulty in determining which nodules to sample for fine-needle aspiration (FNA) cytology has prompted the introduction of the Thyroid Imaging Reporting and Data Systems (TIRADS), which assesses the malignancy risk associated with thyroid nodules. Real-time elastography (RTE), coupled with strain ratio (SR) measurements, offers a means to evaluate the nodule stiffness and potentially discern their likelihood of being malignant. The present study aimed to investigate the efficacy of RTE and SR, combined with the TIRADS grading systems, in distinguishing between benign and malignant thyroid nodules.
methodsFrom 1094 patients with thyroid nodules referred for thyroid ultrasound at a University Hospital, those with thyroid nodules ≥20 mm in diameter were enrolled. Each nodule was categorized according to European (EU)- and American College of Radiology (ACR)-TIRADS systems, ranging from 2-5. Nodules' SRs were evaluated together with RTE. The thyroid nodule diagnosis was documented by post-thyroidectomy histopathological examination and/or US-guided FNA according to the Bethesda classification of the examined smears.
resultsThe study involved 267 patients (mean age 60.3 ± 14.3 years; 46 males and 221 females) with 308 nodules categorized into EU-TIRADS categories 3, 4, and 5. Of these nodules, 22 proved malignant, and 286 benign. The elastography ratio exhibited high predictive performance in diagnosing thyroid malignancy (p < 0.001) at a threshold value of >0.84 (sensitivity 90.9%, specificity 73.4%). In the 168 nodules with EU-TIRADS 3, this threshold had 100% sensitivity and 75.1% specificity in discriminating malignant thyroid nodules.
conclusionCombining TIRADS with data derived from RTE reduces unnecessary FNAs and surgeries in patients with thyroid nodular disease.
