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
Breast cancer is one of the leading causes of cancer globally. Radiotherapy following breast-conserving surgery is the standard treatment of breast cancer. Recently, hypofractionated irradiation comprising 42.56 Gy in 16 fractions was selected as a viable radiation therapeutic option. Radiation-induced sarcoma is the most prevalent secondary malignancy in patients undergoing radiotherapy after breast cancer surgery. Angiosarcomas are the predominant type of radiation-induced sarcomas, whereas liposarcomas have rarely been reported. The present report details an uncommon instance of radiation-induced pleomorphic liposarcoma that occurred 8 years after breast-conserving surgery and hypofractionated radiotherapy. The patient visited the hospital due to hardening of the tissue beneath the skin of the right breast. Ultrasonography revealed a hypoechoic mass in the lower part of the right breast containing internal blood flow. An excisional biopsy revealed that the tumor contained infiltrating spindle-shaped cells without a capsule containing pleomorphic cells. Lipoblasts were also observed and tended to differentiate into adipose tissue, leading to a diagnosis of pleomorphic liposarcoma. Immunostaining revealed negativity for cytokeratin AE1/AE3, ERG, MDM2 and S-100 protein; the Ki-67 index was ~20%. An enlargement resection involving a postoperative bed was performed because of close tumor margins.
