Are few amino acid positions in rpoB associated with most of the rifampin resistance in Mycobacterium tuberculosis?
Highly accurate regression and classification models of rifampin resistance can be made based on this short sequence region. Models may be better with improved (and consistent) measurements of MIC and more sequence data.
Some deaths that are conventionally attributed to surgery are not being attributed to the cancer for which the surgery was performed. Although the estimated effect of this misclassification on overall cancer mortality is modest, it may be indicative of more widespread confusion about how to code treatment-related deaths of patients with cancer.
