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
backgroundLaparoscopic liver resection (LLR) can be challenging due to the difficulty of establishing a retrohepatic tunnel under laparoscopy. Dissecting the third hepatic hilum before parenchymal transection often leads to significant liver mobilization, tumor compression, and bleeding from the short hepatic veins (SHVs). This study introduces a novel technique utilizing the ventral avascular area of the inferior vena cava (IVC), allowing SHVs to be addressed after parenchymal transection, thereby reducing surgical complexity and improving outcomes in in situ LLR.
aimTo introduce and evaluate a novel LLR technique using the ventral avascular area of the IVC and compare its short-term outcomes with conventional methods.
methodsThe clinical cohort data of patients with pathologically confirmed hepatocellular carcinoma or intrahepatic cholangiocarcinoma who underwent conventional LLR and novel LLR between July 2021 and July 2023 at the First Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. In novel LLR, we initially separated the caudate lobe from the IVC using dissecting forceps along the ventral avascular area of the IVC. Then, we transected the parenchyma of the left and right caudate lobes from the caudal side to the cephalic side using the avascular area as a marker. Subsequently, we addressed the SHVs and finally dissected the root of the right hepatic vein or left hepatic vein. The short-term postoperative outcomes and oncological results of the two approaches were evaluated and compared.
resultsA total of 256 patients were included, with 150 (58.59%) undergoing conventional LLR and 106 (41.41%) undergoing novel LLR. The novel technique resulted in significantly larger tumor resections (6.47 ± 2.96 cm
conclusionThis novel technique enhances liver resection outcomes by reducing intraoperative complications such as bleeding and tumor compression. It facilitates a safer,
