Relative sensitivities at different sampling rates. For each choice of standard reference (rows), the data were then downsampled to various levels (columns) and the relative sensitivity calculated (i.e. the proportion of HFOs detected at the lower rate). The top row is the 5 kHz gold standard used for the rest of the paper. Values are given as mean with standard error of the mean in parenthesis. Note, the 5 kHz row is identical to Fig. 1A and uses all 17 patients, whereas the higher sampling rate rows (10, 15, 20 kHz) utilize only 24 hours each of three patients (UM-05, UM-07, UM-08).
