Comparative long-term efficacy of short-term spinal cord stimulation versus bipolar pulsed radiofrequency for refractory postherpetic neuralgia: a 24 month prospective study.
Observational study in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPostherpetic neuralgia (PHN) is a debilitating neuropathic pain condition that persists after herpes zoster infection, often resistant to conventional medications. This study compares the long-term efficacy and safety of short-term spinal cord stimulation (stSCS) versus bipolar pulsed radiofrequency (bPRF) in managing refractory PHN.
methodsIn this prospective, controlled observational study, 140 PHN patients (aged ≥ 18 years; PHN duration ≥ 3 months) with inadequate pain relief from standard therapies were enrolled and randomized equally into two groups (n = 70 each). The stSCS group received percutaneous implantation of an 8-contact electrode for temporary neuromodulation, while the bPRF group underwent application of controlled high-frequency pulses to the dorsal root ganglion. Outcome measures included pain intensity (VAS, NRS), neuropathic pain characteristics (DN4), quality of life (SF-36, EQ-5D), sleep quality (PSQI), and psychological status (SAS, SDS), assessed at baseline and at follow-up intervals over 24 months.
resultsBoth stSCS and bPRF achieved significant short-term pain relief. However, from 6 to 24 months post-treatment, the stSCS group demonstrated significantly lower VAS scores and superior pain control compared to the bPRF group. In addition, improvements in sleep quality and emotional well-being were more pronounced in the stSCS group at 12, 18, and 24 months. Both treatments exhibited favorable safety profiles with only minor, transient adverse events reported.
conclusionsWhile both stSCS and bPRF effectively alleviate pain in patients with refractory PHN, stSCS offers superior long-term benefits in pain reduction, sleep quality, and psychological outcomes. These findings suggest that stSCS may be the preferred neuromodulation strategy for patients with chronic PHN requiring sustained symptom management.
