Prognostic analysis and clinical characteristics of osteosarcoma and Ewing sarcoma of the rib, sternum, and clavicle: a SEER-based study.
Article in The Journal of international medical research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
objectiveOsteosarcoma and Ewing sarcoma of the rib, sternum, and clavicle are rare tumor entities, and their clinical features and treatment outcomes have been rarely reported. The present study was performed to evaluate their survival and confirm independent survival predictors.
methodsData on patients with osteosarcoma or Ewing sarcoma of the rib, sternum, and clavicle from 1973 to 2016 were retrospectively extracted from the database. Univariate and multivariate Cox regression analyses were used to determine the independent risk factors. Kaplan-Meier survival curves were applied to examine the prognostic difference between the groups.
resultsIn total, 475 patients with osteosarcoma or Ewing sarcoma of the rib, sternum, and clavicle were eligible for this study, including 173 (36.4%) with osteosarcoma and 302 (63.6%) with Ewing sarcoma. The 5-year overall survival and cancer-specific survival rates of all patients were 53.6% and 60.8%, respectively. Six independent variables were identified, including age at diagnosis, sex, histological grade, metastatic status, tumor type, and surgery.
conclusionsSurgical resection is a reliable treatment for osteosarcoma and Ewing sarcoma of the rib, sternum, and clavicle. Further research is needed to reconfirm the role of chemotherapy and radiotherapy in survival of these patients.
