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
Purpose: Standard methods for percutaneous transhepatic portal vein embolization have not yet been established. This study aimed to elucidate the effectiveness of balloon occlusion in percutaneous transhepatic portal vein embolization using gelatin sponges on the hypertrophy ratio of the future liver remnant volume. Material and Methods: This retrospective study included 93 patients who underwent percutaneous transhepatic portal vein embolization for right hepatectomy between January 2018 and September 2022. Based on the embolization procedure, patients were divided into a balloon group (n = 13) and a non-balloon group (n = 80). The clinical factors and future liver remnant volume hypertrophy ratios were compared. Moreover, significant factors associated with the future liver remnant volume hypertrophy ratio between the groups were analyzed. Results: The future liver remnant volume hypertrophy ratio was significantly higher in the balloon group than in the non-balloon group (1.44 [interquartile range, 1.37-1.89] vs. 1.29 [1.15-1.46], p = 0.011). The initial future liver remnant volume (289 [interquartile range, 259-454] vs. 400 [324-479] mL, p = 0.036) and number of gelatin sponge sheets (5 [interquartile range, 5-6] vs. 4 [3-5], p = 0.008) significantly differed. However, recanalization and severe complications were not different between groups. According to the multivariate linear regression analysis, diabetes mellitus (coefficient, -0.202, p = 0.009), initial future liver remnant volume (coefficient, -0.001, p < 0.001), and balloon occlusion (coefficient, 0.228, p = 0.007) were independent factors affecting the future liver remnant volume hypertrophy ratio. Conclusions: Balloon occlusion may be effective in future liver remnant volume hypertrophy in percutaneous transhepatic portal vein embolization using gelatin sponges.
