In publishing our longitudinal studies, we customarily table and graph in multiples of 30 days. In figures, for example, our major tick marks are at multiples of 360 days. No journal has objected to this.

Hi all, similiar to the last question, I'm trying to get the results of a outcome (in this case smoking=0 not smoking=1) 6 months from an initial date (the patients first clinic visit). The date is coded in the format <10sep2008> in stata. Is it possible to do this? Thank in advance for any help.

Sure.

newdate=visitdate1+6*30
merge patid newdate using outcomes, keep(result)

Best, Sergiy
