Comparison of the Efficacy and Safety of Temporary Spinal Cord Stimulation versus Pulsed Radiofrequency for Postherpetic Neuralgia: A Prospective Randomized Controlled Trial

Figure 3

Comparison of the patient-reported results over time between the SCS (n = 20) and PRF (n = 20) cohorts (median, quartile). (a) Marked difference in VAS between the two cohorts at the 1 week, as well as 1-, 3-, and 6-months follow-ups. . (b) Considerable difference in SIS between the two cohorts at the 1 week, as well as the 1-, 3-, and 6-month follow-ups. . (c) Massive difference in PHQ-9 between the two cohorts at the 6-month follow-up, . (d) Remarkable difference in GAD-7 between the two cohorts at the 1-, 3-, and 6-month follow-ups, . (e) Considerable difference in PF of SF-36 between the two cohorts at the 3- and 6-month follow-ups, . (f) Marked difference in BP of SF-36 between the two cohorts at the 1 week, as well as, at 1-, 3-, and 6-month follow-ups, . Error bars refer to the 1st and 3rd quartiles.
