Mean pre-treatment intensities of itch and pain. Participants were asked to rate itch and pain intensities on a numerical rating scale (NRS, 0–10). Mean intensities (with standard error of the mean; SEM) of itch and pain are presented separated by insect species and (A) sex of participants, and (B) age of participants. Colours from light green to dark red indicate milder to more severe ratings. **p < 0.01; ***p < 0.001, CL_A = 0.57, (H₀:μ_female = μ_female); CL_B(itch) = 0.39, CL_B(pain) = 0.41 (H₀:μ_19-25 = μ_36-45 and H₀:μ_26-35 = μ_56-65, respectively).
