Postoperative Chemical Radiculitis Mimicking Recurrent Disc Herniation: 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
Early recurrence of radicular pain after lumbar discectomy is commonly attributed to recurrent disc herniation; however, non-compressive inflammatory mechanisms such as chemical radiculitis should also be considered. We report the case of a 30-year-old patient who underwent L5-S1 discectomy for S1 radiculopathy with motor deficit, with an initially favorable postoperative course and complete pain relief. Three weeks later, the patient developed severe recurrent S1 radicular pain without any new neurological deficit. Magnetic resonance imaging suggested recurrent disc herniation, leading to surgical re-exploration, which revealed no evidence of recurrent herniation or hematoma but instead an inflamed and swollen S1 nerve root. The patient was subsequently managed conservatively, with progressive resolution of symptoms. This case highlights the importance of recognizing chemical radiculitis as a potential cause of early postoperative radicular pain to avoid unnecessary reoperation.
