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

purposeAttempt to identify the beneficial effects associated with surgical procedures on survival outcome of patients with recurrent cholangiocarcinoma.

methods921 patients diagnosed with cholangiocarcinoma underwent surgical resection with curative intent in a single institute during the last 15 years. Patients with recurrent disease were divided into two groups according to whether surgical procedures were performed for the treatment of recurrence. Clinicopathologic variables, ranges of survival based on sites of recurrence, and types of treatment were analyzed retrospectively.

resultsThe median follow-up period was 21.8 months and 316 (34.3%) patients had recurrence. 27 (group A) patients with recurrent disease were treated surgically and 289 patients (group B) were not treated. Liver resection, metastasectomy, pancreaticoduodenectomy, partial pancreatectomy, and regional lymph node dissection were performed on the patients in group A. The overall survival rate was statistically higher in group A (P = 0.001). Among the surgical procedures, resection of locoregional recurrences (except liver) in abdominal cavity (4.0 to 101.8 months vs. 0.6 to 71.6 months) and metastasectomy of abdominal or chest wall (3.5 to 18.9 months vs. 1.9 to 2.2 months) showed remarkable differences with respect to the range of survival.

conclusionBetter survival outcomes can be expected by performing surgical resection of locoregional recurrences (except liver) in abdominal cavity and abdominal or chest wall metastatic lesions in recurrent cholangiocarcinoma.
