Topical capsaicin 8% patch in peripheral neuropathic pain: Efficacy and quality of life.
Article in British journal of pain, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Introduction: Peripheral neuropathic pain (PNP) is one of the most challenging diseases to treat with a significant negative impact on the patients' health-related quality of life (HRQoL). Capsaicin 8% patch has arisen in the last decades as an alternative to oral drugs in the treatment of PNP with fewer side effects and promising results in efficacy. Objectives: This work aims to evaluate the effectiveness of the topical application of capsaicin in PNP and its impact on patients' HRQoL based on the use of capsaicin in a tertiary hospital of Oporto. Methods: This study included 100 patients with localized PNP with poor pain control and without improvement with previous treatments that were treated at least once with an 8% capsaicin patch. Effectiveness on pain relief, number of treatments needed, safety and impact on HRQoL were assessed through a set of questionnaires. Results: Regarding the aetiology of PNP, 67.6% ( Conclusion: Capsaicin 8% patch is effective in PNP treatment at least in the short term. Repeated applications may be important for long-term analgesia. The low systemic dose and few side effects mean that the treatment is generally well tolerated by patients. Due to the analgesic effect, capsaicin can improve the HRQoL of patients with PNP.
