Efficacy and safety of balloon kyphoplasty compared with non-surgical care for vertebral compression fracture (FREE): a randomised controlled trial.
Douglas Wardlaw,Steven R. Cummings,Jan Van Meirhaeghe,Leonard Bastian,John Tillman,Jonas Ranstam,Richard Eastell,Peter Shabe,K. Talmadge,Steven Boonen +9 more
TL;DR: The findings suggest that balloon kyphoplasty is an effective and safe procedure for patients with acute vertebral fractures and will help to inform decisions regarding its use as an early treatment option.

Zoher Ghogawala,James Dziura,William E. Butler,Feng Dai,Norma Terrin,Subu N. Magge,Jean-Valery Coumans,J. Fred Harrington,Sepideh Amin-Hanjani,J. Sanford Schwartz,J. Sanford Schwartz,Volker K.H. Sonntag,Fred G. Barker,Edward C. Benzel +13 more
TL;DR: Among patients with degenerative grade I spondylolisthesis, the addition of lumbar spinal fusion to laminectomy was associated with slightly greater but clinically meaningful improvement in overall physical health-related quality of life than lamin surgery alone.

Measurement of health status: Ascertaining the minimal clinically important difference
TL;DR: An approach to elucidating the significance of changes in score in quality of life instruments by comparing them to global ratings of change is developed, and a plausible range within which the minimal clinically important difference (MCID) falls is established.

Interpretation of changes in health-related quality of life the remarkable universality of half a standard deviation
TL;DR: In most circumstances, the threshold of discrimination for changes in health-related quality of life for chronic diseases appears to be approximately half a SD, which research in psychology has shown is approximately 1 part in 7.
