Beck EC, Gowd AK, White JC, et al. - A nested case-control study was conducted to compare variations in 1-year functional outcomes and rates of achieving meaningful clinically important differences between current smokers and non-smokers who had undergone lumbar tubular microdecompression for lumbar spinal stenosis. Between January 2014 through August 2019, researchers recruited a total of 183 patients who had undergone single-level lumbar tubular microdecompression by a single surgeon. They recorded preoperative and postoperative patient-reported outcomes using the questionnaires EQ-5D, Oswestry Disability Index, and the visual analog scale for back pain and leg pain. They further applied meaningful clinically important differences.
