Note. a=Pearson correlation, b= Kendall’s tau correlation.

c

Measured using the PROMIS Emotional Distress-Fatigue-Short From (SF) 8a; possible scores range from 8 to 40, with higher scores indicating greater fatigue.

d

Measured using the University of California, Los Angeles-Loneliness Scale-revised; possible scores range from 20 to 80, with higher scores indicating greater loneliness.

e

Measured using the Epworth Sleepiness Scale; possible scores range from 0 to 24, with higher scores indicating greater tendency of having fallen asleep or dozed off.

f

Measured using the Perceived Stress Scale; possible scores range from 0 to 40, with higher scores indicating greater perceived stress.

ER, estrogen receptor; ERDR, estrogen receptor down regulator; SERM, selective estrogen receptor modulator.
