Long-term survival and risk factors in esophageal squamous cell carcinoma: A Kaplan-Meier and cox regression study.
Article in World journal of gastrointestinal surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe global incidence of esophageal cancer (EC) remains high. Despite advancements in medical technology and deeper research into the causes and treatment methods of EC, the effectiveness of treatment for EC is still unsatisfactory. Therefore, it is crucial to address the urgent problem of improving the long-term survival rate of EC patients and providing personalized treatment.
aimTo analyze the survival prognosis and influencing factors of esophageal squamous cell carcinoma (ESCC).
methodsA retrospective analysis was conducted on the clinical data of 115 patients with pT3N0M0 ESCC who underwent radical surgery alone from January 1, 2013, to December 31, 2019. The Kaplan-Meier method was used to evaluate the 1-year, 3-year, and 5-year survival rates and median survival time of the patients. The Cox proportional hazards regression model was used to assess the hazard ratios (HRs) and 95% confidence intervals (95%CIs) of risk factors.
resultsThe 1-year, 3-year, and 5-year overall survival (OS) rates for the 115 EC patients analyzed were 85.22%, 50.43%, and 37.48%, respectively. The median OS was 37.00 (95%CI: 24.93-49.07) months, and the median disease-free survival was 21.00 (95%CI: 14.71-27.29) months. Both univariate and multivariate Cox regression analyses revealed that high body mass index (BMI; HR = 1.137, 95%CI: 1.054-1.226), positive perineural invasion (PNI; HR = 13.381, 95%CI: 4.899-36.547), and smoking (HR = 2.415, 95%CI: 1.388-4.203) were independent risk factors for a poor prognosis. In contrast, compared to the upper thoracic location of the tumor, middle thoracic (HR = 0.441, 95%CI: 0.240-0.810) and lower thoracic (HR = 0.328, 95%CI: 0.144-0.750) locations were protective factors.
conclusionBMI, tumor location, PNI, and smoking are associated with the prognosis of ESCC patients. This study highlights the prognostic risk factors for T3N0M0 ESCC patients and offers personalized insights for clinical treatment.
