Clinic CBC Results
| File Name | Data as of | Population | Data collected | One row per | Rows |
|---|---|---|---|---|---|
| cbc_ctos_inv.dat | 8/29/2014 | CT+OS | Baseline, Main | Specimen Draw | 236,089 |
ID - WHI Participant Common ID Col 1
CBCDAYS - CBC Days since randomization/enrollment Col 2
CBCVTYP - CBC Visit type Col 3
CBCVY - CBC Visit year Col 4 Visit year for which this CBC was collected.
CBCVCLO - Closest to visit within visit type and year Col 5 For forms entered with the same visit type and year, indicates the one closest to that visit's target date. Valid for forms entered with an annual visit type. Usage Notes: See data preparation document.
CBCEXPC - Expected for visit Col 6 This data was expected for this visit. CBC results were expected for CT at Baseline and for OS at Baseline and at Annual Visit 3. Usage Notes: This includes forms from the subsample of OS participants at year 6 that were enrolled in the three clinical centers participating in the WHI Osteoporosis sub study, as height and weight were collected on OS participants at year 6 by design; see table 16.1; on page 16-18b of volume 2.
SAMEDRAW - All CBC results from same draw indicator Col 7 Flag indicating if all the CBC results reported are from the same draw.
HEMATOCR - Hematocrit (%) Col 8
HEMOGLBN - Hemoglobin (gm/dl) Col 9
PLATELET - Platelet count (Kcell/microliter) Col 10
WBC - White blood cell (Kcell/microliter) Col 11

This file includes the results from blood collected at a screening visit (and for OS participants, Annual Visit 3) and analyzed at each Clinical Center’s (CC) local laboratory. * Broad range checks have been applied to the CBC results to exclude biologically implausible values. Extreme values and inconsistencies between results may still exist. * Data are missing if the lab was unable to process the sample. * Careful inspection of the CBC result data is recommended before using these results in analyses. * NOTE: WBC differential data are not available in the WHI Clinic CBC Results. While individual clinics may have assessed WBC differential, the results were not entered into the WHI database.
