Taste blindness for PTC has been studied in (a) 416 leprosy patients and 424 healthy subjects, and (b) 261 filarial patients and 136 normal individuals of both sexes. A significant difference was found between leprosy patients and the healthy control group in the proportion of nontasters (χ2 = 4.096, for 1 DF, P〈0.05). No significant difference could be observed between the filariasis and the control group (χ2 = 0.605, for 1 DF, P〉0.30).
