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

We report a rare case of huge amebic intra-abdominal tumor with asymptomatic amebic colitis. This appears to represent the first report of amebic intra-abdominal tumor. A 31-year-old woman presented to a local doctor with only a sensation of abdominal fullness. Abdominal computed tomography (CT) showed a huge intra-abdominal tumor in the left abdominal cavity, and she was referred to our hospital. Colonofiberscopy for detailed examination showed multiple slight, discrete ulcers in the cecum. Ameboid trophozoites were identified from biopsy specimens, and asymptomatic amebic colitis was diagnosed. Oral metronidazole (MTZ) was administered at 1500 mg/day for 10 days. CT 14 days after starting MTZ showed no change in the intra-abdominal tumor, and resection of the tumor was therefore performed. Pathological examination revealed Entamoeba histolytica with engulfed erythrocytes complicated by hemorrhagic cyst. If an intra-abdominal tumor is present and colitis is observed, amebic intra-abdominal tumor should be considered among the differential diagnoses.
