[EX Q]: Question: Is the absolute nucleated red blood cell ( aNRBC ) count at birth an indicator for retinopathy of prematurity ( ROP )?
Answer: We are unable to support the previously reported relationship of aNRBCs with ROP. Our population was three times larger, had higher aNRBCs and less retinopathy than previously reported. A biological principle of cause and effect or predisposition to ROP as reflected by aNRBCs should have been easier for us to demonstrate, if it existed.
[EX A]: no

[EX Q]: Question: Do resident involvement and experience affect perioperative complications following robotic prostatectomy?
