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

A 56-year-old man presented with weight loss, abdominal pain, and altered bowel habits. Computed tomography revealed an appendiceal mass with hepatic lesions and regional lymphadenopathy, suggestive of advanced appendiceal malignancy. Surgical exploration identified a mucin-producing appendiceal tumor with metastatic involvement of the mesentery, liver, and lymph nodes. Histopathological examination confirmed an invasive, moderately differentiated mucinous adenocarcinoma of the appendix, without lymphovascular or perineural invasion. The mesenteric lesion showed malignant neoplastic cells consistent with metastatic appendiceal adenocarcinoma, infiltrating the surrounding tissue. The patient underwent surgical resection followed by systemic chemotherapy. During follow-up, clinical evolution was consistent with advanced metastatic disease requiring ongoing multidisciplinary management. This case highlights the diagnostic and therapeutic challenges of advanced appendiceal mucinous adenocarcinoma and emphasizes the importance of complete pathological characterization and coordinated oncologic care.
