1 · What the graph read from it

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.

2 · The registry

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

purposeEndocrine surgery encompasses various organ systems, but thyroid surgery represents the major component. The Japanese Association of Thyroid Surgeons published nationwide data on thyroid cancer surgery until 2005, since when no further reports have been published. Thus, we analyzed thyroid surgery trends using data from the National Clinical Database (NCD) from 2014 to 2023.

methodsWe analyzed cases of thyroid surgery, for malignant and benign conditions, recorded in the NCD. A detailed analysis of papillary thyroid carcinoma (PTC) cases was conducted in 2014, 2019, and 2023 to assess TNM classification, surgical procedures, complications, and outcomes.

resultsThe number of thyroid surgery facilities and the number of thyroid surgeries being performed have both declined since 2020. A trend toward more hemithyroidectomies and fewer total thyroidectomies for PTC is evident. The number of surgeries for cancers < 1 cm and lateral node dissection for PTC have also decreased. Endoscopically assisted surgery has increased continuously, accounting for > 4% of thyroid operations in 2020. The incidence of permanent hypoparathyroidism has decreased and perioperative mortality is rare.

conclusionThe changes in surgical trends are aligned with guideline updates and shifts in surgical practice. Future efforts will refine data collection and utilize the NCD to improve thyroid surgical quality and research.
