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
backgroundTo investigate the effect of surgical approaches for hepatic inflow occlusion performed during hepatectomy on postoperative tumor-free survival (TFS) in patients treated with R0 resection.
methodsIn total, 343 hepatocellular carcinoma (HCC) patients who underwent hepatectomy (R0) with different surgical approaches for hepatic inflow occlusion were analyzed retrospectively.
resultsIn total, 68.80% of the patients underwent hepatic inflow occlusion, including 46.65% with a routine Pringle maneuver and 22.16% with selective hemi-hepatic vascular exclusion (SHVE), during surgery. The TFS did not significantly differ among the Pringle group, the SHVE group and the no hepatic inflow occlusion group. After further stratifying the patients according to the Barcelona clinic liver cancer (BCLC) staging system, the patients with BCLC stage A disease in the SHVE group and no hepatic inflow occlusion group displayed better TFS than those in the Pringle maneuver group (P=0.04; P=0.002), but the patients with BCLC stage B-C disease did not show significant differences among the groups. Furthermore, all 214 patients with BCLC stage A disease were classified into two subgroups according to the microvascular invasion (MVI) status. Interestingly, among the patients with MVI, those in the SHVE group and no hepatic inflow occlusion group had significantly longer TFS than those in the Pringle group (P=0.025; P=0.006); however, the patients without MVI did not show differences among the groups. Additionally, the multivariate analysis revealed that a tumor size ≥5 cm, an absent capsule, a low Edmondson grade, MVI positivity and performance of the Pringle maneuver were independent risk factors of the prognosis in patients with BCLC stage A disease.
conclusionsHepatic inflow occlusion and the surgical approach used to address this issue may have an impact on HCC prognosis in patients with BCLC stage A disease, especially among those with MVI positivity. No hepatic inflow occlusion or an SHVE approach rather than the Pringle maneuver should be considered first during hepatectomy for patients with BCLC stage A disease.
