Figure
Odds ratios and 95% confidence intervals for postoperative outcomes in patients who underwent surgery for far lateral lumbar disc herniation. OR <1 indicates the event is more likely for the open cohort. OR >1 indicates the event is more likely for the endoscopic cohort. Red values denote statistical significance (P < 0.05). ED, emergency department.
