validating counts and percentages

[keen_sas]

How do you validate listings and tables in clinical trial data.? How do u validate or ensure the counts and percentages obtained in a table (clinical trial table) are correct?Can anyone please explain it with an example?

Generally you would have someone else QC the data by writing their own programs independently of yours. If you do not come up with the same numbers you would want to confer and see where the difference occurs. You would also want someone to go through your listings and check that all the counts add up/look sensible.
