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

backgroundPreoperative portal vein embolization (PVE) is performed for right liver (RL) and sometimes left liver (LL) resection to prevent postoperative surgical complications.

methodsWe retrospectively reviewed 10 patients who underwent preoperative left PVE before LL resection for hepatobiliary malignancies along with 3 propensity score-matched control groups (n = 40 each).

resultsMean patient age was 68.6 ± 6.9 years. Diagnoses included intrahepatic cholangiocarcinoma (n = 4), perihilar cholangiocarcinoma (n = 3), neuroendocrine carcinoma (n = 1), recurrent cholangiocarcinoma (n = 1), and inflammatory liver mass (n = 1). The reason for left PVE was a large LL >40 % of the total liver volume (TLV) with a major comorbidity or age > 70 years with a poor overall condition. All patients underwent preplanned operations, including LL resection at 1-3 weeks post PVE. The LL volume proportion of the TLV was 44.9 ± 1.7 and 40.7 ± 2.3 % before and after PVE; thus, 1-2 weeks post PVE, the kinetic shrinkage rate of the LL was 9.4 ± 3.3 %, and the kinetic growth rate of the RL was 7.6 ± 2.7 %. The overall surgical complication rates were 40, 50, and 39.2 % in the left PVE, large LL control, and all three control groups, respectively (p ≥ 0.727). In contrast, the adjusted rates of major complications were 0 % in the left PVE group versus 36.8 % (p = 0.040), 25.6 % (p = 0.123), and 15.8 % (p = 0.295) in the large-, medium-, and small-sized LL control groups, respectively.

conclusionsOur experience indicates that left PVE is safe and induces atrophy of the LL effectively. We suggest that it can be a useful option to reduce the risk of postoperative complications in elderly high-risk patients.
