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

backgroundBlood transfusion is linked to a negative outcome for malignant tumors. The aim of this study was to evaluate aggressive surgical resection for hilar cholangiocarcinoma (HCCA) and assess the impact of perioperative blood transfusion on long-term survival.

methodsSixty-six consecutive major hepatectomies with en bloc resection of the caudate lobe and extrahepatic bile duct for HCCA were performed using macroscopically curative resection at our institute from 2002 to 2012. Clinicopathologic factors for recurrence and survival were retrospectively assessed.

resultsOverall survival rates at 1, 3, and 5 years were 86.7, 47.3, and 35.7 %, respectively. In univariate analysis, perioperative blood transfusion and a histological positive margin were two of several variables found to be significant prognostic factors for recurrence or survival (P<0.05). In multivariate analysis, only perioperative blood transfusion was independently associated with recurrence (hazard ratio (HR)=2.839 (95 % confidence interval (CI), 1.370-5.884), P=0.005), while perioperative blood transfusion (HR=3.383 (95 % CI, 1.499-7.637), P=0.003) and R1 resection (HR=3.125 (95 % CI, 1.025-9.530), P=0.045) were independent risk factors for poor survival.

conclusionsPerioperative blood transfusion is a strong predictor of poor survival after radical hepatectomy for HCCA. We suggest that circumvention of perioperative blood transfusion can play an important role in long-term survival for patients with HCCA.
