1 · What the graph read from 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.

2 · The registry

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

Background: A patient with von Willebrand disease developed a delayed epidural hematoma originating from the tunneling tract and gluteal generator pocket following the placement of a thoracic spinal cord stimulator (SCS). Case Description: A 43-year-old male with von Willebrand disease underwent thoracic SCS placement to treat chronic bilateral lower extremity pain with paresthesias in 2024. The patient had previously experienced a postoperative hematoma in 2010. At the time of the thoracic SCS placement, he received 7 days of prophylactic antihemophilic factor/von Willebrand factor complex therapy. One month following placement of the thoracic SCS, the patient noted significant swelling localized to the thoracic and buttock incisions. Exploratory surgery documented an additional hematoma tracking from the tunneling tract and gluteal generator pocket all the way into the epidural space; it was promptly removed. At the 6-month follow-up, he exhibited no further wounds or neurological issues. Conclusion: Patients with coagulopathies, and critically, von Willebrand disease, undergoing SCS placement are at increased risk for postoperative hematomas.
