Data analysis
FJI
REGRESSION
Descriptive statistics were calculated for participant demographics and clinical characteristics, along with outcome variables (7-day average NPRS and ODI scores) at baseline. Comparisons between treatment groups (C-LRFA vs FJI) were performed using Fisher exact tests for categorical variables and Wilcoxon-Mann-Whitney rank-sum tests for continuous variables.Treatment success rates and corresponding 95% confidence intervals (CIs) were calculated for all outcome measures (≥50% NPRS reduction, ≥2-point reduction in NPRS, ≥50% reduction in OID, and ≥6 on the PGIC). Dichotomous variables representing the proportion of responders for each outcome measure were compared between C-LRFA vs FJI treatment groups at all follow-up time points using contingency table analyses with Mixed-effects binomial logistic regression models
