- Independent variable: type of laminoplasty (groups: mFDL and ODL). The adjusted covariates for the JOA score and its RR were age, sex, BMI, preoperative JOA score, follow-up duration, OPLL type, and K-line. The adjusted covariates for operative time and blood loss were age, sex, BMI, preoperative JOA score, OPLL type, and K-line
- SE standard error, OR odds ratio, CI confidence interval, JOA Japanese Orthopaedic Association, RR recovery rate
- *Grouped by the variables below. Grouped by postoperative JOA score (bounded by ≥ 14), grouped by operative time (bounded by ≥ 90 min), grouped by blood loss (bounded by ≥ 300 mL), grouped by JOA score recovery rate (bounded by ≥ 0.82)
