Change point 1 is the first change point before FMP; change point 2 is the second change point before FMP; change point 3 is the third change point near/at FMP; and change point 4 is the fourth change point after FMP. First window is the time window with slower logFSH change before FMP, which is number of years elapsed from change point 1 to change point 2. Second window is the time window with faster logFSH change around FMP, which is number of years elapsed from change point 2 to change point 4.
