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
objectivesThe purpose of this study was to assess whether trans-lymphatic contrast-enhanced ultrasound (CEUS) combined with sentinel lymph node biopsy can be used to assess the status of cervical lymph nodes and skip metastasis in patients with early squamous cell carcinoma (SCC) of the oral tongue.
methodsThis study included 21 subjects with early oral tongue SCC who received multiple intramucosal peritumoral injections of Sonazoid. CEUS examinations were performed immediately after Sonazoid injection to identify sentinel lymph nodes (SLNs). The SLNs were excised for histological examination to determine if the lymph nodes has metastases.
resultsThirty-five SLNs were detected by CEUS after Sonazoid injection in the subjects. SLNs were identified in 20 of the total 21 subjects. Four participants had metastasis to lymph nodes, and one had skip metastasis in level Ⅲ. In one subject, SLNs were successfully detected in level Ⅳ without skip metastasis.
conclusionsTrans-lymphatic CEUS combined with sentinel lymph node biopsy showed high accuracy for evaluating cervical lymph node status. This could be a reliable approach for detecting cervical skip metastases of lymph nodes in early-stage oral cancer patients.
