How outcomes of clinical trials are reported alters the way treatment effectiveness is perceived: clinicians interpret the outcomes of trials more favourably when results are presented in relative (such as risk ratio) rather than absolute terms (such as risk reduction). However, it is unclear which methods clinicians find easiest to interpret and use in decision making. ⋯ Clinicians stated that additional reporting methods facilitate the interpretation of trial results, and using a variety of methods would make results easier to interpret in context and incorporate into practice. Authors of future back pain trials should report data in a format that is accessible to clinicians.

Two studies, each consisting of large sample sets, were recently published on radiation exposure in percutaneous spinal cord stimulation (SCS) trialing procedures. A more rigorous use of statistical methods in the second study more accurately defined benchmark reference levels. Principally, one physician implanter-considered an advanced interventional pain physician-performed all such procedures to nullify inter-physician variability. However, the literature is sparse in articles comparing exposure levels of radiation in pain procedures conducted by novice and advanced interventionally trained physicians, and inferential statistical analysis is seldom included in radiation exposure studies. ⋯ Radiation exposure levels in SCS trialing procedures remain negligible. While no differences in fluoroscopy times for such procedures were detected based on physician experience, the expert implanter demonstrated the ability to use less fluoroscopy time than that of the benchmark reference level.

Close, impinging and overriding spinous processes in the thoracolumbar spine: the relationship between radiological and scintigraphic findings and clinical signs.
There has been no objective study comparing radiological features of spinous processes (SPs) in the thoracolumbar region and/or scintigraphic findings with clinical signs. ⋯ Fore- or hindlimb lameness and/or pain associated with the sacroiliac joints could mimic primary thoracolumbar pain. A combination of radiology and scintigraphy gives the most accurate prediction of thoracolumbar pain, but diagnostic analgesia is crucial for accurate diagnosis.
