adaptation recovery ratio(English)
- defined as the ratio between the ECAP amplitude measured at the MPI of 256 ms and that measured for the single-pulse stimulus presented at the same stimulation level. The time constants of the ARF were estimated using a mathematical model with an exponential function with up to three components

annualized relapse rate(English)
- a key metric in clinical studies, particularly for Multiple Sclerosis (MS) and NMOSD, representing the average number of relapses a patient experiences per year. It is calculated as the total number of relapses divided by the total person-years in a study, with modern trials often showing lower rates (<0.5) compared to historical data
