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
Umbilical incision implant cancer after LC is rare. Elective cholecystectomy was planned for a 49 years-old female patient with symptomatic gallstones. The patient underwent transumbilical single-port LC after admission to our hospital. Gallbladder specimens were obtained directly through the umbilical puncture hole, and histopathology suggested chronic cholecystitis. Three months after surgery, the patient experienced painful induration in the umbilicus. We initially considered incision scar hyperplasia complicated with pain, and used drugs to treat it conservatively without taking special treatment measures. Six months after LC, the umbilical induration pain affected her quality of life, and the patient requested surgical resection. Preoperative ultrasonography and abdominal computerized tomography (CT) revealed nodular changes around the umbilicus and no abdominal mass. Local resection of the periumbilical mass was performed, and the pathological confirmation was invasive adenocarcinoma. Subsequently, the patient underwent repeat periumbilical mass enlargement resection. Postoperative pathology showed no cancer at the enlarged resection margin, yet the umbilical center pathology showed invasive adenocarcinoma. The excised pathology was sent to the Sun Yat-sen University Cancer Center for consultation because of the rare nature of the findings associated with the case. After consultation, a diagnosis of umbilical urachus adenocarcinoma was confirmed based on pathological morphology, immunohistochemistry, and the specific anatomical location of the tumor. This case report shown that when there is a persistent mass induration in the navel after LC surgery, the possibility of incision tumor should be considered, rather than simply excluding the possibility of a cancer based on a non-cancer medical history.
