  1. A. Average deltamethrin (S-Isomer) content (in g/kg). The target doses at baseline (tolerance limits of ±25%) are 0.8 (0.6-1) g/kg, 1.8 (1.35 -2.25) g/kg and 1.4 (1.05–1.75) g/kg for CTN, Netprotect® and PermaNet® 2.0 respectively. Between-net variation is expressed by the Relative Standard Deviation (RSD%).
  2. B. Deltamethrin R-alpha isomer content.
