  1. Data are absolute values and percentages of positively stained cells in women’s samples for the expression of ER-⍺, ER-β, PR in the supraspinatus tendon: it was quantified considering four grades of diffuse immunoreactivity: 0 = no expression; 1 = weak expression; 2 = high expression; 3 = very high expression
