What was measured

The VAS (visual analogue scale) for pain is on a 10 point scale. Pain is studied with chi-square, Mann Whitney U test, or Fisher's exact test. The pain scale used was 0-10, with 0 being no pain and 10 being the worst pain.

Groups in this outcome

Arm I (Biopsy Using Power Drill)

Patients undergo bone marrow biopsy using the power drill. Patients complete questionnaires at baseline, 30 minutes after biopsy, and on days 1, 3, and 7. Power drill: Undergo bone marrow biopsy using power drill

Arm II (Biopsy Using Jamshidi Needle)

Patients undergo bone marrow biopsy using the traditional Jamshidi needle. Patients complete questionnaires at baseline, 30 minutes after biopsy, and on days 1, 3, and 7. Jamshidi needle: Undergo bone marrow biopsy using Jamshidi needle
