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

backgroundRadiological detection of small liver metastasis or peritoneal metastasis is still difficult, and some patients with biliary tract cancer (BTC) are unresectable after laparotomy. Staging laparoscopy may help avoid unnecessary laparotomy. However, which category of BTC is amenable with staging laparoscopy remains unclear.

aimTo clarify the risk factors for occult metastasis in patients with BTC.

methodsMedical records of patients with BTC who underwent surgery at our institution between January 2008 and June 2014 were retrospectively reviewed. The patients were divided into two groups, according to resection or exploratory laparotomy (EL). Preoperative laboratory data, including inflammation-based prognostic scores and tumor markers, were compared between the two groups. Prognostic importance of detected risk factors was also evaluated.

resultsA total of 236 patients were enrolled in this study. Twenty-six (11%) patients underwent EL. Among the EL patients, there were 16 cases of occult metastasis (7 liver metastases and 9 abdominal disseminations). Serum carcinoembryonic antigen level, carbohydrate antigen 19-9 level, neutrophil-lymphocyte ratio and modified Glasgow prognostic score were significantly higher in the EL group than in the resected group, and these factors were prognostic. Among these factors, carcinoembryonic antigen > 7 ng/mL was the most useful to predict occult metastasis in BTC. When patients have more than three of these positive factors, the rate of occult metastasis increases.

conclusionInflammation-based prognostic scores and tumor markers are useful in detecting occult metastasis in BTC; based on these factors, staging laparoscopy may reduce the rate of EL.
