Random Forest-Based Detection of Metastases in Clinically Scanned Lymph Nodes Using Quantitative Ultrasound Imaging.

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
objectiveQuantitative ultrasound (QUS) imaging has been used to characterize the microstructural properties of tissue using information contained in the backscattered radiofrequency (RF) echo signals. QUS methods were previously applied to detect metastases in excised human lymph nodes (LNs) that were raster scanned using a 30 MHz single-element transducer ex vivo. In the current study, a QUS-based method to detect in vivo LN metastases using a clinical scanner was developed.
methodsParallel RF frames were captured from 46 cervical and axillary LNs in 45 patients and two backscatter coefficient-based and two envelope statistics-based QUS parameters were computed and averaged for each frame. Different combinations of these four QUS parameters, along with the LN's short-axis and short-to-long axis ratio, were used to train random forest models to classify metastatic LNs.
resultsThe average QUS parameters and radiomics features were significantly different between metastatic and benign LNs (p≤10
conclusionThese results demonstrate the potential of QUS imaging using a clinical scanner for identifying metastatic LNs in vivo to help clinicians perform a more selective LN biopsy or excision.
