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

introduction and importanceAnomalous venous drainage of the right upper lobe into the superior vena cava is an uncommon anatomical variation, typically diagnosed incidentally. CASE PRESENTATION: We report the case of a 76-year-old male patient undergoing right upper lobectomy via video-assisted thoracoscopic surgery (VATS) for a primary pulmonary adenocarcinoma, combined with a minimally invasive subtotal esophagectomy for an adenocarcinoma of the gastroesophageal junction. During the thoracic procedure, an anomalous venous drainage of the right upper lobe into the superior vena cava was identified intraoperatively. The patient had no prior respiratory symptoms suggestive of a left-to-right shunt. Surgical management was adapted to account for the vascular anomaly. CLINICAL DISCUSSION: We discuss anomalous venous drainage of the right upper lobe into the superior vena cava is an uncommon anatomical variation which may pose significant challenges during thoracic surgeries.

conclusionThis case highlights the importance of careful intraoperative assessment of vascular anatomy during thoracic oncologic surgery.
