<p>From an osteoporotic cohort of 58,703 patients in a nationwide representative cohort of one million people, 421 patients had percutaneous vertebroplasty (vertebroplasty group; n = 421), while age-, sex- and propensity score-matched patients comprised the comparison group (n = 1,655). The two groups were compared and followed-up for up to five years for subsequent stroke events.</p
