A propensity score matching analysis: Impact of senior resident versus fellow participation on outcomes of complex surgical oncology.
Article in Surgical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTeaching hospitals that train both general surgery residents and fellows in complex general surgical oncology have become more common. This study investigates whether participation of a senior resident versus a fellow has an impact on outcomes of patients undergoing complex cancer surgery.
methodsPatients who underwent esophagectomy, gastrectomy, hepatectomy, or pancreatectomy between 2007 and 2012 with assistance from a senior resident (post-graduate years 4-5) or a fellow (post-graduate years 6-8) were identified from the ACS NSQIP. Based on age, sex, body mass index, ASA classification, diagnosis of diabetes mellitus, and smoking status, propensity-scores were created for odds of undergoing the operation assisted by a fellow. Patients were matched 1:1 based on propensity score. Postoperative outcomes including risk of major complication were compared after matching.
resultsIn total, 6934 esophagectomies, 13,152 gastrectomies, 4927 hepatectomies, and 8040 pancreatectomies were performed with assistance of a senior resident or fellow. After matching, overall rates of major complications were equivalent across all four anatomic locations between cases performed with the participation of a senior resident versus a surgical fellow: esophagectomy (37.0%% vs 31.6%, p = 0.10), gastrectomy (22.6% vs 22.3%, p = 0.93), hepatectomy (15.8% v 16.0%, p = 0.91), and pancreatectomy (23.9% vs 25.2%, p = 0.48). Operative time was shorter for gastrectomy (212 vs. 232 min; p = 0.004) involving a resident compared to a fellow, but comparable for esophagectomy (330 vs. 336 min; p = 0.41), hepatectomy (217 vs. 219 min; p = 0.85), and pancreatectomy (320 vs. 330 min; p = 0.43).
conclusionsSenior resident participation in complex cancer operations does not appear to negatively impact operative time or postoperative outcomes. Future research is needed to further assess this domain of surgical practice and education, particularly with regard to case selection and operative complexity.
