Note: Age at time of brushing, whether or not the patient received a stem cell transplantation (SCT), detection of CNAs and mutations in the brushed sample, the follow‐up time and the location of the tumor, if applicable, were recorded. Follow‐up from the date of sample collection until the occurrence of OSCC, death, or last moment of follow‐up.

^a Short time to progression (<3 months).
