Osteoradionecrosis of the craniotomy flap: a rare complication of stereotactic radiosurgery.
Article in Oxford medical case reports, 2022. 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
Osteoradionecrosis (ORN), ischemic necrosis of irradiated bone without evidence of persisting or recurrent tumor, is a known complication of radiation therapy. ORN of the skull has not been reported following stereotactic radiosurgery (SRS). We report two cases of ORN of the skull following SRS for recurrent meningiomas post-resection. Both patients developed ORN in their craniotomy flaps in areas that received high doses of radiation due to their proximity to the recurrent tumors. In each case, the ORN was asymptomatic and was detected on surveillance magnetic resonance imaging. Both patients were followed closely with imaging that ultimately revealed either stability or improvement in the ORN, confirming the diagnosis without the need for biopsy. The cases reveal a role for close imaging surveillance instead of immediate biopsy in patients with new enhancement involving bone in high-dose radiation treatment regions.
