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
Background: Extraskeletal osteosarcoma is an uncommon and high-grade soft tissue malignancy. The incidence is even lower when the skin is the primary site. To the best of our knowledge, the primary cutaneous osteosarcoma has fewer than 30 reported cases worldwide, which with decreased copy number of Case presentation: A 28-year-old man was hospitalized for a skin mass on the left shoulder. The histological examination showed a large number of tumor giant cells and fibroblasts, and nuclear division was easy to see. Immunohistochemistry showed positive for CK, EMA, S100, CD34, CK7, Bcl-2, ACTin, and NSE, and negative for Vim, SATB2, CD99, SMA (focal), and Ki67 was about 40%. Shoulder joint CT and PET-CT showed that no metastasis presented. Germline testing showed decreased copy number of Conclusions: Primary cutaneous extraskeletal osteosarcoma (PC-EOS) is rare, and preoperative differential diagnosis is difficult. This is the first report of PC-EOS with decreased copy number of
