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

backgroundEndoscopic papillectomy is increasingly performed as an alternative to surgery for early ampullary tumors.

aimThis retrospective study aimed to evaluate the long-term results of endoscopic papillectomy, the management of cases with incomplete endoscopic resection, and the long-term recurrence rates.

methodsAll 46 patients who underwent endoscopic papillectomy for ampullary tumors between November 2003 and March 2018 were retrospectively evaluated.

resultsThe final pathological diagnoses were adenoma (n = 44) and adenocarcinoma (n = 2). Histopathological evaluations after endoscopic papillectomy revealed that complete resection was achieved in 19 patients (19/46, 41.3%). Among the 27 patients with incomplete resection, the margin was histopathologically positive in 14 patients and difficult to evaluate in 13. Additional surgery was performed for 2 of the 14 patients with positive margins. Excluding 2 patients who received additional surgery, 7 of the 25 patients with incomplete resection had recurrence, and 18 had no recurrence during the follow-up period. Ten (77%) of the 13 patients in whom the margin was difficult to evaluate had no recurrence.

conclusionApproximately 80% of the patients in whom the histopathological evaluation of the resected margin was difficult had no recurrence even after approximately 5 years of follow-up. Thus, careful observation may be considered for these patients.
