Esophageal cancer surgery in Ethiopia: postoperative mortality and long-term survival.

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
Introduction: Cancer remains the leading cause of death worldwide, with esophageal cancer being the sixth leading cause of cancer-related deaths. For individuals with esophageal cancer, esophagectomy is the most effective treatment option available and has a high risk of both death and morbidity. Moreover, despite advances in preoperative optimization, surgery, and anesthesia techniques as well as the introduction of neoadjuvant therapy, the mortality and morbidity associated with esophagectomy remain high. Objective: To assess the survival status and predictors of postoperative survival in patients who underwent esophageal surgery for esophageal malignancies at selected hospitals from to 2018-2023 in Ethiopia, Addis Ababa. Methods: This was a retrospective cohort study. After acquiring data from the chart review, the data were analyzed using R version 4.3.3. Descriptive statistics for categorical variables were reported as frequencies and percentages. Kaplan-Meier curves and log-rank tests were used to estimate the survival curve and the difference in survival among groups within each covariate. After esophageal surgery, the impact of each covariate on time to death was assessed using the Cox proportional hazard model. Results: One hundred eighty-three patients who underwent esophageal surgeries for esophageal malignancy at four governmental hospitals in Addis Ababa over 5 years were included. The mean age was 53.8 years. 120 (65.6 %) had a tumor size <3.3 cm, and squamous cell carcinoma accounted for 154 (84.2 %) cases. Epidural analgesia was the most commonly used analgesic technique, 40 (21.9 %). The 30-day mortality was 10.9 %. The overall 1-, 2-, 3-, 4-, and 5-year survival rates were 53 %, 30.6 %, 19.5 %, 19.5 %, and 13 %, respectively. The median survival was 17 months. ASA score of > III (AHR = 2.14, 95 % CI: 1.12-4.12), cervical anastomotic leak (AHR = 3.29, 95 % CI: 1.44-7.52), and sepsis (AHR = 3.70, 95 % CI: 1.46-9.38) were identified as predictors of postoperative mortality in the multivariate Cox regression model. Conclusion: In Ethiopia, patients who underwent surgery for esophageal cancer had low 5-year survival rates.
