Technical Pearls
Today's news:
- Chris Cates has released a new version of his wonderful software, Visual RX:
- "What’s New?
In the 2004 Updated version of Visual Rx the Confidence Interval (CI) for the calculated Number Needed to Treat (NNT) can be generated by entering the upper and lower CI for the Odds Ratio or Relative Risk on the data entry screen. The CI for the NNT will then be displayed on the second smiley face screen. The rounding is always up to the next integer when calculating NNT (so 3.1 will round up to 4)."
