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

Background: Although lymph node metastasis may be an adverse prognostic factor for survival after resection of thymic epithelial malignancies, recommendations for intraoperative lymph node dissection (LND) lack consistency across various guidelines. This study aimed to investigate feasibility and characteristics of LND. Methods: This is a work-in-progress report of our prospective, multi-institutional observational study to evaluate the feasibility and characteristics of LND in patients with resectable thymic epithelial malignancies that exhibit radiological invasive features such as size >5 cm, standardized uptake value >5, or suspected invasion of surrounding organs. Results: In total, 25 patients were enrolled in this study. All patients underwent complete resection of the primary lesion with N1-level or N2-level LND. Among these, 22 (88%) patients underwent N1-level LND, and 20 (80%) patients underwent N2-level LND. No significant differences between the open and minimally invasive approaches were observed in the number of dissected stations (P=0.71), N1-level LND (P=0.49), or N2-level LND (P=0.69). Conclusions: Intraoperative LND may be feasible in both approaches and may contribute to accurate nodal staging in resectable thymic malignancies with radiologically invasive features.
