How is the TFMR percentage calculated?

Explanation:
TFMR percentage is a proportion that shows how often the TFMR categories occur out of all possible outcomes. You combine the two TFMR components (FMR and PMR) in the numerator, and in the denominator you include all three outcomes (FMR, PMR, and NMR) so you’re normalizing by every case. In other words, TFMR percentage = (FMR + PMR) / (FMR + PMR + NMR). This yields a value between 0 and 1 (0% to 100% when expressed as a percent). Example: if there are 2 FMR, 3 PMR, and 5 NMR, TFMR = (2+3) / (2+3+5) = 5/10 = 0.5, or 50%. Other forms would misrepresent by omitting a component in the numerator or denominator, which would distort the true share of TFMR cases.
