1 · What the graph read from it

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.

2 · The registry

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

introductionMyelolipomas are rare tumors containing adipose tissue and normal hematopoietic cells that mainly occur in the adrenal cortex. Mediastinal myelolipomas are extremely rare. The three-dimensional, high-definition view with up to 10 times image magnification, 7 degrees of freedom of surgical instruments, and filtration of physiologic hand tremors with robotic systems are ideal for removing mediastinal tumors in a small space. Herein, we report a case of posterior mediastinal myelolipoma treated using robotic resection. CASE PRESENTATION: A 72-year-old man with an abnormal shadow on a chest roentgenogram was referred to our hospital. Computed tomography revealed extrapulmonary paravertebral lesions in the right posterior mediastinum. Despite the tumor's fragility, complete resection was achieved with robot-assisted thoracic surgery while preserving the lesion integrity. The tumor was diagnosed as a myelolipoma using histopathology of the resected section, and the patient was discharged with no complications on the fifth postoperative day. CLINICAL DISCUSSION: Mediastinal myelolipomas are fragile tumors with a thin capsule, consisting of adipose tissue and normal hematopoietic cells. Robot-assisted thoracic surgery is particularly effective for resecting posterior mediastinal tumors like myelolipomas that contain adipose components.

conclusionsWith delicate manipulation, robot-assisted thoracic surgery can be used to safely and completely resect fragile posterior mediastinal tumors, including myelolipomas.
