Article in Anesthesia and pain medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06956664 (Comparative Efficacy of Physiotherapeutic Exercise Regimens Implemented After Caudal Epidural Steroid Injection), which is not on this map. Cited by 4 papers, 1 of them a synthesis that pooled it.

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.

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.

Abstract

backgroundSpinal epidural hematoma is rare condition that can rapidly develop into severe neurologic deficits. The pathophysiology of this development remains unclear. There are several case reports of emergency hematoma evacuations after epidural steroid injection. CASE: We report on two patients who developed acute, large amounts of epidural hematoma without neurological deficits after transforaminal epidural steroid injection. After fluoroscopy guided aspiration for epidural hematoma was performed, neurological defects did not progress and the hematoma was shown to be absorbed on magnetic resonance imaging.

conclusionsThese reports are believed to be the first of treating epidural hematoma occurring after transforaminal epidural steroid injection through non-surgical hematoma aspiration. If large amounts of epidural hematoma are not causing neurological issues, it can be aspirated until it is absorbed.
