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.
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
backgroundPortal vein embolization (PVE) is often performed prior to right hemihepatectomy (RH) to increase the future liver remnants. However, intraoperative removal of portal vein thrombus (PVT) is occasionally required. An algorithm for treating the right branch of the PV using laparoscopic RH (LRH) after PVE is lacking and requires further investigation.
methodsIn our department, after the confirmation of a lack of extension of PVT to the main portal trunk or left branch on preoperative examination (ultrasound and contrast-enhanced computed tomography), a final evaluation was performed using intraoperative ultrasonography (IOUS). Here we present the cases of eight patients who underwent LRH after PVE and examine the safety of our treatment strategies.
resultsIOUS revealed PVT extension into the main portal trunk in two cases. For the other six patients without PVT extension, we continued the laparoscopic procedure. In contrast, in the two cases with PVT extension, we converted to laparotomy after hepatic transection and removed the PVT. The median operation time for hepatectomy was 562 min (421-659 min), the median blood loss was 293 mL (85-1010 mL), no liver-related postoperative complications were observed, and the median length of stay was 10 days (6-34 days).
conclusionsPVT evaluation and removal are important in cases of LRH after PVE. Our strategy is safe and IOUS is particularly useful for laparoscopically evaluating PVT extension.
