Hi,
I have a data with glucose levels at admission and at discharge in 2 different variables. I want to calculate the P-value for the difference in means between these 2 variables. It means, I want to test if there was a significant change in the glucose level with time in this population.
Thanks
Variable
HBA1C_ADM
HBA1C_DIS
Mean
7.1
6.5
SD
1.0
0.8
PROC TTEST or PROC ANOVA
Check both of the examples sections.
I think, this should be a PAIRED T-Test, so make sure you decide explicitly if it's paired or not.

@seltonsy So what is your question to us? Which part, specifically, are you having issues with?
sorry if it wasn't clear enough,
I'd like to know what is the proc to use that can perform this test. Compre the means of the two variables and provide p-values (i.e. if the means of the 2 variables are significantly different or not).
Thanks in advance.

Thanks,
Paired t test is the right answer I guess,
Here is what I did,
proc ttest data=cohort_1 ;
paired HBA1C_ADM*HBA1C_FIN;
run;
