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

purposeThis study aimed to identify prognostic factors for patients with ICC after a curative resection and clarify the appropriate indications for surgical resection and postoperative adjuvant chemotherapy.

methodsThis retrospective study included 81 patients who underwent curative resection for ICC between April 1995 and December 2014. Kaplan-Meier and Cox regression models were used to analyze the effects of clinicopathological features on overall and recurrence-free survival.

resultsThe cumulative 5-year overall survival of 81 patients was 57.2%, and the 5-year recurrence-free survival was 24.0%. The multivariate analysis identified the lymph node status and preoperative CA19-9 levels as independent prognostic factors for overall survival. The 5-year overall survival rates were 79.9% and 38.7% in patients with normal and elevated CA19-9, respectively (p < 0.0001). The 5-year overall survival rates of patients with and without nodal metastasis were 33.7% and 60.9%, respectively (p = 0.0007). After adjusting for prognostic factors identified in a Cox regression analysis, we found that nodal-positive disease was significantly associated with benefit from adjuvant chemotherapy (HR 0.32, p = 0.03).

conclusionsSurgical resection with curative intent combined with regional lymph node dissection should be indicated for ICC patients with normal CA19-9 levels. Postoperative adjuvant chemotherapy should be administered to high-risk patients with a positive nodal status.
