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/objectives: Postoperative adjuvant therapy for esophageal squamous cell carcinoma (ESCC) primarily includes chemotherapy and chemoradiotherapy. The survival benefits of postoperative adjuvant therapy for R0-resected ESCC remain controversial. Immunotherapy is being gradually applied perioperatively for esophageal cancer, but the efficacy of postoperative immunotherapy in ESCC is unclear. This study aimed to evaluate the effectiveness of postoperative immunotherapy for esophageal cancer. Toward this goal, we explored the differences between postoperative immunotherapy combined with chemotherapy and postoperative adjuvant chemotherapy alone. Methods: This retrospective study evaluated patients who underwent radical surgery for esophageal cancer at Gaozhou People's Hospital between January 2020 and August 2022 and received postoperative adjuvant therapy. Patients were divided into two groups according to the adjuvant treatment regimens: postoperative adjuvant chemotherapy (aCT) and postoperative adjuvant immunotherapy combined with chemotherapy (aICT) groups. Data on baseline characteristics, surgical-related indicators, adverse event rates during adjuvant therapy, and 2-year postoperative follow-up were collected for both groups. Results: A total of 76 patients were included: 36 and 40 patients in the aICT and aCT groups, respectively. There were no significant differences in baseline data between the two groups. During the adjuvant treatment period, the incidence of hypothyroidism was significantly higher in the aICT group than in the aCT group (25.0% vs. 2.5%, Conclusion: For patients with pathologically confirmed locally advanced ESCC after surgery, postoperative immunotherapy did not confer better disease-free recurrence rates compared to postoperative adjuvant therapy. Nonetheless, with research advancements, the role of immunotherapy in the treatment of ESCC is likely to expand, offering new hope for these patients.
