We see your misleading NCDB analysis.

And raise you another. A whole host of radiation oncologists were disturbed by the NCDB analysis concluding that radiofrequency ablation (RFA) results in longer overall survival than stereotactic radiation (SBRT) for inoperable hepatocellular carcinoma (HCC). So they performed another NCDB analysis including only those receiving adequate SBRT doses to show no difference in survival...right before concluding that survival should never be an endpoint in the first place when using databases with so little info on such big confounders. | Shinde, J Clin Oncol 2018
