Overall survival of patients stratified by the presence or absence of each one of the specific cytogenetic abnormalities showing statistical significance. The significance values are expressed next to each curve and correspond to the log-rank test. The x-axis values represent time since diagnosis, which is expressed in months. The results for the t(11;14)(q13;q32) are not shown, as they were not statistically significant. The thicker lines represent patients without the specific abnormality.
