Serotonin-Norepinephrine Reuptake Inhibitors in Fibromyalgia Management: An Integrative Literature Review of Clinical Evidence.
Review in Clinics and practice, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
Fibromyalgia (FM) is a chronic pain syndrome characterized by central sensitization and impaired pain modulation, involving dysfunctional descending inhibitory pathways and altered nociceptive processing. These processes contribute to persistent musculoskeletal pain, difficulties with sleep, feelings of depression, and ongoing fatigue. Serotonin and norepinephrine are key mediators of pain control, and evidence indicates that dual reuptake inhibition provides superior analgesia compared to single-pathway approaches. Accordingly, serotonin-norepinephrine reuptake inhibitors (SNRIs), including milnacipran and duloxetine, approved for FM treatment, show favorable efficacy and tolerability compared with tricyclic antidepressants. This integrative literature review aimed to evaluate the impact of SNRIs on musculoskeletal pain, fatigue, depression, and quality of life in patients with FM by analyzing randomized clinical trials (RCTs), identified via PubMed/MEDLINE searches (2015-2025) in English/Portuguese using descriptors: "Fibromyalgia", "Serotonin and Norepinephrine Reuptake Inhibitors", "Duloxetine" and "Milnacipran". From 195 records screened, 18 studies met inclusion criteria (9.2% inclusion rate); duloxetine evaluated in 16 studies (88.9%), milnacipran in 2 (11.1%); SNRIs demonstrated superior efficacy vs. placebo: pain reduction 30-40%, fatigue improvement 25%, quality of life enhancement 20%. SNRIs were overall more effective than placebo but did not achieve high levels of analgesia, underscoring the need for further research on long-term efficacy and comparisons with combination pharmacological and non-pharmacological therapies. SNRIs significantly alleviate musculoskeletal pain (30-50% of patients), fatigue, depression symptoms, and improve quality of life in FM versus placebo. Duloxetine showed superior efficacy for pain/depression; milnacipran excelled in sleep quality. Long-term studies and combination therapies warrant further investigation.
