A systematic review and meta-regression analysis of prophylactic gabapentin for postoperative pain (2015)
Journal Article
Doleman, B., Heinink, T., Faleiro, R., Lund, J. N., & Williams, J. P. (2015). A systematic review and meta-regression analysis of prophylactic gabapentin for postoperative pain. Anaesthesia, 70(10), https://doi.org/10.1111/anae.13179

We searched MEDLINE, Embase, CINAHL, AMED and CENTRAL databases until December 2014 and included 133 randomised controlled trials of peri-operative gabapentin vs placebo. Gabapentin reduced mean (95% CI) 24-h morphine-equivalent consumption by 8.44 (... Read More about A systematic review and meta-regression analysis of prophylactic gabapentin for postoperative pain.

Study investigating the role of skeletal muscle mass estimation in metastatic spinal cord compression (2015)
Journal Article

Creatinine and myoglobin are poor predictors of anaerobic threshold in colorectal cancer and health (2015)
Journal Article
