Description
Hi,
I am working on the Nurse Health Assessment database (nurse and blood) combined to the full main interview. I only have included participants from wave 2.
I would like to analyze biomarkers and I need to adjust for the time of day the blood was taken.
I searched for such variable and I think the most appropriate variable is b_strtnurhh. The point is I obtained some people who have started the interview at 1 AM. Among 9,884 individuals, there are 73 in this case.
Here, there is STATA results:
table(b_strtnurhh, useNA="always")
1 2 3 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 NA
73 1 1 2 1 3 47 566 1360 1076 583 610 837 725 750 792 1134 1037 258 27 1 0Should I identify these cases as missing values or is it a mistake and I can correct them by 1 PM ?
Thank you for helping me.

Dear Gaelle,
Please accept my apologies for the delay in getting back to you about this. We have gone back to the fieldwork agency who conducted the nurse visits to ask about these timetamps.
Unfortunately you cannot assume that this should be 1pm - the timings of these interviews could actually be anything as the incorrect timestamp is due to incorrectly set clocks on the nurses' laptops.
Best wishes, Victoria.
