PROC PSMATCH: How to get the standardized mean differences (Treated - Control)?

[withyin]

Could anyone tell me how to get the standardized mean differences in Figure 98.6: Standardized Mean Differences from the linked example, please?

https://documentation.sas.com/?docsetId=statug&docsetTarget=statug_psmatch_gettingstarted.htm&docset...

I can get the matched mean difference 0.16814 for age, but cannot figure out how to get the matched standardized mean difference 0.02766 in Figure 98.6. 

Thanks,

The formulas used in the standardized mean difference computations for matched data are described in the Standardized Mean Differences for Matched Observations section of the PROC PSMATCH documentation. By default the pooled standard deviation estimate derived from all observations is used for the standardization. The value used for standardization is also reported in the "Standard Deviation" column of the table. For the variable Age in that example it is 6.079104.
