Online survival analysis software to assess the prognostic value of biomarkers using transcriptomic data in non-small-cell lung cancer.
In the last decade, optimized treatment for non-small cell lung cancer had lead to improved prognosis, but the overall survival is still very short. To further understand the molecular basis of the disease we have to identify biomarkers related to survival. Here we present the development of an onli...
