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

backgroundIntrahepatic cholangiocarcinoma (ICC) is a heterogeneous hepatobiliary cancer with limited treatment options. A number of studies have illuminated the relationship between inflammation-based prognostic scores and outcomes in patients with ICC. However, the use of reliable and personalized prognostic algorithms in ICC after resection is pending.

aimTo assess the prognostic value of the gamma-glutamyltransferase to lymphocyte ratio (GLR) in ICC patients following curative resection.

methodsICC patients following curative resection (2009-2017) were divided into two cohorts: The derivation cohort and validation cohort. The derivation cohort was used to explore an optimal cut-off value, and the validation cohort was used to further evaluate the score. Overall survival (OS) and recurrence-free survival (RFS) were analyzed, and predictors of OS and RFS were determined.

resultsA total of 527 ICC patients were included and randomly divided into the derivation cohort (264 patients) and the validation cohort (263 patients). The two patient cohorts had comparable baseline characteristics. The optimal cut-off value for the GLR was 33.7. Kaplan-Meier curves showed worse OS and RFS in the GLR > 33.7 group compared with GLR ≤ 33.7 group in both cohorts. After univariate and multivariate analysis, the results indicated that GLR was an independent prognostic factor of OS [derivation cohort: hazard ratio (HR) = 1.620, 95% confidence interval (CI): 1.066-2.462,

conclusionThe preoperative GLR is an independent prognostic factor for ICC patients following hepatectomy. A high preoperative GLR is associated with worse OS and RFS.
