The influence of late retirement on health outcomes among older adults in the policy context of delayed retirement initiative: an empirical attempt of clarifying identification bias

Table 3 The comparison of difficulty in physical functioning and cognitive status between groups of late retirees and non-late retirees

	Obs.	Mean	S. D.	95% CI	T-value of the diff.	p-value
Sample 1: difficulty in physical functioning (2018)
Late retirees (2015)	4791	1.567	0.555	[1.916, 1.956]	27.863	0.000
Non-late retirees (2015)	5236	1.937	0.748	[1.552, 1.583]
Sample 2: problems of cognitive status (2018)
Late retirees (2015)	4168	3.559	0.628	[3.540, 3.578]	5.321	0.000
Non-late retirees (2015)	4499	3.632	0.649	[3.614, 3.651]

Notes: The comparison between late retirees and non-late retiree is based the observations for which the independent variable (i.e., late retirement status) has non-missing values. Thus, the number of observations with non-missing value shown here is not exactly as that shown in Table 2 which has excluded observations with missing value in covariates
