 VAS= Visual Analog Scale;NTS 2= score attributed to nipple damage degree comprised between scores 0-2;NTS 3= score assigned to nipple damage degree comprised between scores 3-5.It is noteworthy that the agreement degree among evaluators in the nipple damage degree classification by NTS was 93.6%. The Kappa coefficient value for internal reliability was considered almost perfect (k= 0.82).The association between initial nipple damage size and evaluators’ classification regarding damage degree by NTS revealed to be statistically significant. The greater the median size of the nipple damage, the greater the tissue damage degree (p<0.001).Regarding nipple damage degree and nipple pain score, it was observed that the median pain of women with a superficial damage with or without a scab formation in less than 25% of the nipple surface (NTS 2) was higher when compared to the median of pain reported by women with a superficial damage with or without a scab formation on more than 25% of the nipple surface (NTS 3), but without statistical significance.No associations were observed between nipple pain score and the moment of occurrence of nipple damage with degree of nipple damage according to NTS.Associations between dependent variables are shown in
