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

objectiveTo identify the MRI characteristics of ovarian metastases from appendiceal tumors (OMAT) and compare them with the features of primary ovarian mucinous carcinoma (POMC). MATERIALS AND

methodsThis retrospective study included 49 patients with histopathologically confirmed, MRI-detectable, and unruptured OMAT (14 patients with 18 lesions) or POMC (35 patients with 36 lesions) who underwent preoperative MRI. Clinical and MRI findings of the two groups were reviewed and compared.

resultsOMATs were smaller than POMCs (median diameter, 129 vs. 182 mm, p < 0.01). Lesion configurations differed between OMATs and POMCs, with the following distributions: purely solid (11% vs. 0%), solid with cystic components (17% vs. 0%), cystic with mural nodules (11% vs. 61%), and purely cystic (61% vs. 39%) (p < 0.01). Among cystic lesions, faint septa (94% vs. 31%, p < 0.01) were more frequent in OMATs than in POMCs, whereas T1-hyperintense cysts (25% vs. 81%, p < 0.01) and a stained-glass appearance (25% vs. 72%, p < 0.01) were less frequent in OMATs than in POMCs. Peritoneal dissemination (71% vs. 11%, p < 0.01) and abnormal ascites (93% vs. 11%, p < 0.01) were also more frequent in OMATs than in POMCs.

conclusionOMATs tended to present as smaller, purely cystic lesions with faint septa, whereas POMCs were characterized by larger cystic lesions with T1-hyperintense cysts and a stained-glass appearance.
