*The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
CI: confidence interval; HDCT: high‐dose chemotherapy; HR: hazard ratio; HSCT: hematopoietic stem cell transplantation; SDCT: standard‐dose chemotherapy.

GRADE Working Group grades of evidence
High quality: Further research is very unlikely to change our confidence in the estimate of effect.
Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
Very low quality: We are very uncertain about the estimate.

*Soft tissue sarcomas: tumor entities not listed in either versions of the WHO classification (Fletcher 2002; Fletcher 2013), or soft tissue tumors not categorized as malignant are italicized. Myoepithelioma is categorized as an intermediate soft tissue tumor. Melanoma and endometrial stromal sarcoma are not listed in the classification.
