This from US News & World Report. This writer really gets what we're striking for with the paper. He prefaces his piece with the dilemma clinicians face when they have an effective, but toxic drug that works for a few patients, but they don't know which patients. So they have to just go at it trial-and-error, exposing some patients to toxicity without benefit in the process.
What we hope our method will help people do in the future is to help patients and physicians understand the "which?" question.
