BRD2 and Dysmenorrhea: Therefore, by correlation analysis with six kinds of hormone levels and dysmenorrhea integrals, we have established a regression equation: Y = 1.15125 + 0.24804X1 + 0.19443X2 + 0.26509X3 + 0.20469X4 − 0.32597X5 + 0.05783X6 (Y, dysmenorrhea inregrals; X1, PRL; X2, FSH; X3, LH; X4, TEST; X5, PROG; X6, E2).
