High-grade

"The high-grade ore was much more profitable than lower-grade ore."

"This chapter on high-grade pelvic prolapse by Phillip Toozs Hobson and Amallia Brair concisely reviews prevalence, risk factors, conservative and surgical management options, surgical complications and prevention. High-grade prolapse is a particularly challenging clinical scenario because it reflects a severe loss of native support and has been associated with a higher rate of recurrence over time. Pelvic prolapse is an intimate condition in which education and counselling is critical to patient’s understanding, expectations and treatment satisfaction."
