Comparison of MDS and t-MDS patient accrual across groups A, B, and C. The patient accrual on the y-axis represents the MDS and t-MDS patients who were accrued in trials that also had affiliated published works (either abstract or manuscript) within the past 20 years. Group A trials excluded t-MDS patients, group B mentioned neither the exclusion nor inclusion of t-MDS patients, and group C trials included t-MDS patients.
