Stellate Ganglion Block for Post-acute Sequelae of SARS-CoV-2 Infection With Coexisting Post-traumatic Stress Disorder, Anxiety, and Chronic Pain: A Case Report.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Post-acute sequelae of SARS-CoV-2 infection (PASC), commonly referred to as long COVID, is characterized by persistent symptoms, including fatigue, cognitive dysfunction, pain, and neuropsychiatric complaints, that can impair daily functioning. Proposed mechanisms are heterogeneous and may include autonomic dysregulation in a subset of patients. Stellate ganglion block (SGB) is a cervical sympathetic block used to treat symptoms of post-traumatic stress disorder (PTSD), anxiety, and, more recently, PASC. A 58-year-old man with a history of attention-deficit/hyperactivity disorder, generalized anxiety disorder, obsessive-compulsive disorder, autism spectrum disorder, PTSD, and chronic musculoskeletal pain developed persistent post-COVID symptoms following infection in March 2020, including brain fog, slowed information processing, word-finding difficulty, worsening anxiety, impaired balance, and reduced hand-eye coordination that significantly impaired occupational functioning as a chef. In January 2023, sequential left- and right-sided SGBs one week apart were performed to address cognitive dysfunction, fatigue, pain, and anxiety. Follow-up documentation described marked improvement in anxiety, frustration tolerance, and cognition lasting approximately six months. Repeat right-sided SGBs were performed in December 2024 and September 2025 for recurrence of symptoms and were again associated with symptomatic improvement. This is the first case demonstrating both longitudinal and reproducible functional improvement in cognitive symptoms, anxiety, and pain following serial SGBs in a patient with PASC complicated by psychiatric comorbidity and chronic pain. Although emerging observational literature suggests potential benefit of SGB in selected patients with PASC, prospective controlled studies are required to determine efficacy, mechanisms, and long-term outcomes.
