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
Purpose: This study aimed to evaluate changes in the extent of surgery and radioactive iodine (RAI) use in patients with papillary thyroid carcinoma (PTC) in South Korea between 2012 and 2017. Methods: A retrospective, multicenter cohort study was conducted using data from 15 tertiary hospitals. Variables included extent of thyroidectomy, lymph node dissection, and RAI use. Trends were evaluated annually. Patients with recurrent disease, non-PTC histology, or missing data were excluded, and temporal trends were assessed using linear-by-linear association. Results: Among 27,625 patients, total thyroidectomy decreased from 72.7% to 40.8%, while lobectomy increased from 27.1% to 57.3%. Central neck dissection remained >90%, while RAI use dropped from 41.4% to 17.4%. Tumor diameter gradually increased over time, with a shift toward higher tumor-node-metastasis stages. Conclusion: A shift toward conservative surgery and reduced RAI use in patients with PTC reflects guideline-based deescalation of thyroid cancer treatment in South Korea. These findings demonstrate substantial changes in the real-world management of PTC across tertiary hospitals during the study period.
