In using PROC QUANTreg the output includes "95% confidence limits" for the parameter estimates. Could you explain what this is, and how to use it in reporting results?

Thanks!

P.S. Excerpt from SAS code:

proc QUANTreg ci=sparsity/iid algorithm=interior(tolerance=1.e-4)
data=SASUSER.bb2014oct;
where age eq 60;

model PUTRL =
pipopera ann_ppt /
quantile=0.2 0.4 0.6 0.8
plot=quantplot;
run;
