Petroclival meningioma regression after combined oestrogen and nomegestrol acetate interruption.
Article in BMJ case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Meningioma regression after progestin treatment interruption is already established. Zoely is a combined oral contraceptive including oestradiol and progestin (nomegestrol acetate). The effect of combined oestrogen with nomegestrol acetate on meningioma is currently unknown. We report the case of a woman in her early 50s under Zoely for 5 years who was diagnosed with a large petroclival meningioma. After cessation of Zoely, the patient showed clinical improvement and shrinkage of the tumour volume from 27.22 cm
