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

backgroundTransaxillary robotic thyroidectomy (TART) has become increasingly adopted for differentiated thyroid cancer (DTC), yet long-term locoregional recurrence patterns remain insufficiently defined. Therefore, we aimed to characterize recurrence patterns using a compartment-based anatomic mapping approach in a large TART cohort.

methodsWe retrospectively analyzed 10,504 patients with DTC who underwent TART at a single institution from 2007 to 2024. Recurrence occurred in 97 patients (0.9%). Anatomic sites included the central compartment (CC), ipsilateral lateral neck (ILN), contralateral lateral neck (CLN), contralateral thyroid (CT), and extracompartmental (EC) regions. Temporal trends and clinicopathologic factors were evaluated. Logistic regression analyses were performed to determine factors associated with ILN and CC recurrence.

resultsRecurrence was single site in 89.7% (n = 87) and multi-site in 10.3% (n = 10). ILN was the most frequent recurrence site (n = 48), followed by CT (n = 38) and CC (n = 12; 7 ipsilateral and 5 contralateral). ILN recurrence was independently associated with N1a disease (adjusted OR 9.70, 95% CI 3.22-33.08; p<0.001), whereas N1b status was not significant after adjustment. In contrast, CC recurrence was strongly associated with baseline nodal burden, particularly N1b disease (p<0.001), and demonstrated symmetric subsite distribution. EC recurrence was rare (n = 3) and occurred within 5 years postoperatively. Median follow-up was 67 months (IQR 56-91).

conclusionsRecurrence after TART demonstrated compartment-specific patterns. CC recurrence was strongly associated with N1b disease and showed a symmetric subsite distribution, whereas ILN recurrence was independently associated with N1a disease. These findings suggest a dominant role of nodal biology in recurrence distribution, although a contribution from technical factors cannot be entirely excluded. Risk-adapted long-term surveillance may therefore be warranted according to baseline nodal status.
