Accuracy of dual-contrast gastrointestinal ultrasonography in predicting lymph node metastasis in older adults with gastric 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
backgroundGastrointestinal dual-contrast ultrasonography (DCUS) is characterized by its high resolution, sensitivity, and specificity.
aimTo determine the accuracy of DCUS in predicting lymph node metastasis in middle-aged and elderly patients with gastric cancer (GC).
methodsA total of 100 middle-aged and elderly patients with GC admitted to the Fourth Affiliated Hospital of Soochow University (Dushu Lake Hospital, Suzhou, China) between April 2022 and April 2024 were selected. The baseline data and lymph node metastasis status were collected. DCUS combined with intravenous contrast technology was used to calculate the enhancement time (ET), time to peak (TTP), and slope of the ascending branch wash-in rate (WIR). These indicators were used in assessing lymph node metastasis in patients with GC.
resultsAmong 100 middle-aged and elderly patients with GC, 35 (35.00%) had lymph node metastases. GC patients with lymph node metastasis had a higher proportion of stage II TNM classification and higher WIR values than those without lymph node metastasis. The ET and TTP values were lower in patients with lymph node metastases, and all differences were statistically significant (
conclusionDCUS-mediated assessment of ET, TTP, and WIR can effectively predict and evaluate lymph node metastasis status in patients with GC, with higher sensitivity when used in combination.
