Intraoperative Contrast-Enhanced Ultrasonography (Io-CEUS) to Detect Missed Lung Nodules During Robot-Assisted Thoracoscopic Surgery.
Article in Thoracic cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Herein, we reported the use of Intraoperative-Contrast Enhanced Ultrasonography (Io-CEUS) during Robotic Assisted Thoracic Surgery (RATS) for identification of malignant lung nodule that was missed during previous operation. Pre-operative CT scan with 3D reconstruction defined the prompt position of the target lesion within S8 segment of right lower lobe and the anatomic landmarks as the distance from interlobar fissure and diaphragm. The lesion was then successfully detected by Io-CEUS. The different arterial enhancement observed during wash-in (hyperenhancement) and wash-out (hypo-enhancement) phases helped to differentiate the nodule from lung parenchyma. The lesion was resected by mechanical stapler and frozen section analysis diagnosed metastasis from colon carcinoma. Post-operative course was unremarkable; patient was discharged on post-operative day 3.
