The research included articles from journals Spine, The Spine Journal and Journal of Spinal Disorders and Techniques over a 10-year period. There were 40 manuscripts included in the study. Researchers found:
• 75 percent of studies had at least one inconsistency
• 75 percent titles and 92 percent of abstracts had the word "randomized" but in 37.5 percent the randomization method wasn't described; in 28 percent the description was unacceptable.
• 22.5 percent of abstracts and 47.5 percent of manuscripts had a clearly stated primary outcome.
• 40 percent of abstracts did not include pertinent negatives
• 60 percent of abstracts reported relevant statistically significant results; the remaining did not.
