So I am wondering if what they are looking for is some sort of graph that is a line per-subject situation. Would proc sgpanel be able to do this by that many variables? Should I condense my GCS variables into some sort of cohesive variable? ... View more

Yes, my attempts so far have looked like a mess.   My data right now looks like this: GCS_24hrs (values range from 4 to 15) GCS_Randomization (values range from 8 to 15) GCS_ED (values range from 8 to 15) then I have 1000 subjects.   The purpose of the graph is to show how these scores changed over time between each variable, for each subject. I attempted to do a sort of overlay density plot and it was one of my better attempts, but it still did not look great. ... View more

Yes, we were asked to create a graph to illustrate the relationship of these scores per subject. I am unsure of how to do that without it looking like a total mess! ... View more

I have been asked to create a graph to show Glasgow Coma Scale over a period of time. I have a variable for each GCS at Baseline, GCS at hospital arrival, and GCS at 2 hrs. I need to create a graph that shows these over time per subject. I have 1000 subjects, so is this even a realistic graph?   Any advice is appreciated.   Thank you. ... View more

Creating Graphics for Multiple Variables

I need to create a graph showing values over time by treatment group. Say I am looking at Hemoglobin as my variable. If I have a variable for each Hemoglobin at Baseline, Hemoglobin at 24hrs, Hemoglobin at 48 hrs, and Hemoglobin at 72hrs, and a variable for Treatment ID (Treatment A or Treatment B), is it possible to graph all of these values over time by Treatment ID in SAS?   Thanks! ...

Finding the "time since" in minutes for date and time

I am trying to find the difference in minutes between two events. I have two variables for time and two variables for dates. I first tried both the INTCK function and FLOOR function, which worked well to find the difference in minutes between my time variables. However, this does not account for date changes.   For example, in finding the time between Onset and Randomization: For Subject 1 -  OnsetDate is 2011-05-15 and OnsetTime is 15:00:00.  RandomizationDate is 2011-05-15 and RandomizationTime is 17:36:00. This leaves 156 minutes between Onset and Randomization. For Subject 2 -  OnsetDate is 2011-06-27 and OnsetTime is 21:55:00. RandomizationDate is 2011-06-28 and RandomizationTime is 00:35:00. I need a function that can account for this date change when finding the time difference.   Any advice is much appreciated! ... View more
