Table 4.
The percent difference was calculated by subtracting the TPS dose from the IC dose, normalized by the TPS dose (column 1), or by subtracting the TPS dose from the Mobius dose, normalized by the TPS dose (column 2), or by subtracting the IC dose from the Mobius dose, normalized by the IC dose (column 3).
