Characteristics of multiple esophageal squamous cell carcinomas detected in the surveillance after endoscopic resection.

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
BACKGROUND AND STUDY
aimEndoscopic resection (ER) of esophageal squamous cell carcinoma (ESCC) is an organ-preserving treatment; however, heterochronic carcinomas are often encountered. Most patients are treated using ER; however, for some, this is inadequate and requires additional treatment. We sought to identify the characteristics and frequency of lesions at high risk of metastasis during surveillance based on Lugol-voiding lesion (LVL) grading and esophagogastroduodenoscopy (EGD) intervals.
methodsOf the 1301 patients who underwent ER, 956 underwent surveillance EGD at our hospital for at least 1 year (median, 59 months). We analyzed identified multiple ESCCs to reveal the characteristic of high-metastasis-risk lesions, which was defined ESCC with submucosal or lymphovascular invasion.
resultsIn the 956 patients, 444 multiple ESCCs were identified in 216 patients and the cumulative incidence of multiple ESCCs was 15.4% and 22.9% at 3 and 5 years, respectively, while for high-risk lesions, it was 1.0% and 1.8%. The risk factors for high-metastasis-risk lesions were being female (odds ratio (OR):5.58, 95% confidence interval (CI):1.96-15.9), lesions located in the cervical/upper thoracic esophagus (OR: 4.81, 95% CI:1.80-12.8), and the presence of submucosal tumor (SMT)-like marginal elevation (OR:65.4, 95% CI:11.0-390). No significant differences in the frequency of high-risk lesions were found based on LVL grade at any EGD intervals.
conclusionDuring endoscopic surveillance, attention should be given to the cervical/upper thoracic esophagus and lesions with SMT-like marginal elevation. The frequency of high-metastasis-risk lesions was not different by LVL grade or EGD intervals.
