Effects of the concentration of capsaicin on the magnitude and duration of itch and pricking/stinging. Linear regressions for logarithmic (Lg) values of concentration and the peak magnitude (“Lg peak mag”), duration (Lg duration in minutes, m), and area under the rating curve (Lg AUC) for itch (A, B, and C, respectively) and pricking/stinging (D, E, and F). Dashed lines provide 95% confidence limits. The slope of each line was significantly different from zero (see main text). Significant slopes were not obtained for burning (data not shown).
