Add the -detail- option to your -summarize-s! You are asking for stuff that
Stata only releases upon request :-)

Hi Martin,
Stata/MP 11.0 for Windows (64-bit x86-64)

I tried to adapt the code for means-SD and ttest to medians IQR and
median unsuscefully. Below is the code. I get the p-value for each
variable but not the descriptive statistics.
What am i doing wrong?
Here is the code:
**********************
use "C:\Users\Eduardo\Desktop\HF dataset - August 24,
2009\Longitudinal_lymphocyte_analysis.dta", clear
tempname hdle
capt erase info.dta
postfile `hdle' str10 var Median_0 IQR25_0 IQR75_0 /*
*/ Median_1 IQR25_1 IQR75_1 pval Overallmedian OverallIQR25 OverallIQR75 /*
*/ using info
foreach var of varlist los edad_b fc_ingreso tas_ingreso tad hb leucos
neutrofilos linfocitos monocitos cr acurico colesterol ldl hdl tga na{
sum `var' if !sexo
loc Median_0=r(p50)
loc IQR25_0=r(p25)
loc IQR75_0=r(p75)
sum `var' if sexo
loc Median_1=r(p50)
loc IQR25_1=r(p25)
loc IQR75_1=r(p75)
median `var', by(sexo) exact
local pval=r(p_exact)
sum `var'
post `hdle' ("`var'") (`Median_0') (`IQR25_0') (`IQR75_0') /*
*/ (`Median_1') (`IQR25_1') (`IQR75_1') (`pval') /*
*/ (r(p50)) (r(p25)) (r(p75))
}
postclose `hdle'
use info, clear
l, abbrev(12) noobs sep(0)
*********************************************************
Thisw is the result I got:
+---------------------------------------------------------------------------

One more thing...
The code you sent me for discrete variables:
***
sysuse auto, clear
estpost tab rep for, chi2
esttab ., main(b) aux(colpct) /*
*/ nostar unstack noobs nonum nonote /*
*/ sca("chi2 Chi2 Value" "p corr. p-value") /*
*/ sfmt(%4.3fc) wide compress
***
How do I loop over several variables? I used tab2, firstonly but it
seems estpost doesn't recognize it.
Note: In biomedical sciences these are the traditional way to express
table 1 for the manuscript where you show how baseline characteristics
are distributed over your exposure variable.
I imagine a lot of statalister that work in biomedical science would
take advantage of this automatic process to save time.
I am very grateful of your help and excuse my ignorance in Stata programing.
Best wishes,
Eduardo
