Perivascular epithelioid cell tumour and investigation of genetic susceptibility.
Article in BMJ 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
A patient in her 60s was referred to be investigated for an incidental large uterus with a history of renal cell carcinoma and melanoma. Uterine biopsy revealed features of perivascular epithelioid cell tumours (PEComas) and she underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Final histology confirmed PEComa with malignant features. Genomic studies did not reveal any deleterious germline variants; however, in view of her history, she is now under a 6-month follow-up with gynaecology-oncology. PEComas are rare tumours associated with tuberous sclerosis and melanoma, sharing genetic abnormalities. Gynaecological PEComas usually present with no or non-specific symptoms. Preoperative investigations are often misleading. Final histology and immunohistochemistry have overlapping features with smooth muscle tumours. Although rare, PEComas need to be treated aggressively to minimise the potential risk of spread. There is currently little evidence about further adjuvant treatment and no clear follow-up protocol. However, the literature suggests that the prognosis is generally good.
