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

Intracholecystic papillary neoplasm and cholecystocolonic fistula are both relatively rare diseases. Here, we report a case of a preoperative intracholecystic papillary neoplasm associated with invasive carcinoma and a transverse colonic fistula of the gallbladder. A 79-year-old female patient presented to our hospital with persistent right upper quadrant pain for several months and was suspected to have intracholecystic papillary neoplasm associated with an invasive carcinoma by computed tomography and endoscopic ultrasound. A gallbladder tumor biopsy was pathologically diagnosed as intracholecystic papillary neoplasm. Preoperative cholecystocolonic fistula diagnosis enabled planning not only for cholecystectomy, but also for transverse colon partial resection. Pathological examination of the resected specimen revealed intracholecystic papillary neoplasm associated with an invasive carcinoma with subserosal invasion. No malignant findings were observed in the fistula. This is a rare condition, but the presence or absence of cholecystocolonic fistula should be considered before performing intracholecystic papillary neoplasm surgery.
