The value of ultrasound in diagnosing metastatic internal mammary lymph nodes in preoperative breast cancer.

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
backgroundInternal mammary lymph nodes (IMLNs) metastasis is of great significance for patients with breast cancer (BC), but the diagnosis of metastasis is difficult. The purpose of this study was to explore the characteristics of metastatic internal mammary lymph nodes visualized on breast ultrasound (US) in preoperative breast cancer.
methodsBetween March 2014 and May 2020, a total of 278 patients with primary BC were enrolled in a retrospective study and were divided into a metastatic group (n=224) and a non-metastatic group (n=54) according to IMLN status. Medical records, US findings, and especially IMLN status (long and short diameter, cortical thickness, blood flow) were reviewed, analyzed, and correlated with pathologic results.
resultsThere were significant differences in long diameter, short diameter, numbers, intercostal space (ICS) distribution, and structure type of IMLN between the two groups (P<0.05), but no statistical difference in the ratio of long to short diameter and blood flow (P>0.05). The best cutoff values of size for differentiating IMLN metastasis from benign LNs were 10.5 mm (long diameter), 4.5 mm (short diameter), and 1.9 mm (cortical thickness), with sensitivities of 62.9%, 71.4%, and 91.4%, respectively and specificities of 90.7%, 77.8%, and 86.7%, respectively. The sensitivity and specificity of long and short diameter combined with structure type of IMLN were 74.1% and 83.3%, respectively.
conclusionsUS is an important tool to evaluate the status of IMLN in patients with BC. US features of metastatic IMLNs include thickened cortex (≥1.9 mm), absent fatty hilum, multiple (n≥2). The size (long or short diameter) combined with structural types of IMLN had good efficacy for diagnosing IMLN metastasis.
