Hi all,

I'm using Stata 11 and carrying out a series of Cox regressions for which I save the results into a .dta file using -parmest-. I run the regressions on each level contained within a variable (ICD10) using local levels. What I am trying to do is generate a new variable following parmest, which is equal to the local level for which the regression has just been calculated i.e. before I save the file at the end and run through the next level of ICD10, I want to generate a column that holds the value for the first level of ICD10 and so on in subsequent regressions.

Here is my code:

                levelsof ICD10, local(levels)
                foreach l of local levels {
                di as text "_______________________________"
                                di as text "`l'"
                                                cap noi: xi: stcox delay2v2 `covariates' if ICD10 =="`l'", nolog
                foreach v in delay2v2 { // continuous variables
                                   local l`v' : variable label `v'
                                   if `"`l`v''"' == "" { // if no variable label
                                                                local l`v' "`v'"

                parmest, norestore eform
                foreach v in delay2v2 {
                   replace parm = "`l`v''" if parm == "`v'"
                                replace parm = "baseline odds" if parm == "_cons"
                **Remeove baseline odds
drop if parm =="baseline odds"

gen label2=""
destring label2, replace

**delay group

replace label2 = 101 if parm == "delay2v2"

label values label2 label2

gen flag=""
destring flag, replace
replace flag = 1 if p<0.05
replace flag = 0 if p>=0.05
label define flag 0 "Not significant" 1 "Significant"
label values flag flag
save "T:\mydocuments\cancer_`l'.dta", replace
