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

purposeLittle is known about liver resection (LR) in hepatocellular carcinoma (HCC) patients older than 75 years of age. This study aimed to compare the postoperative and long-term outcomes of hepatectomy in this patient population according to operation period.

methodsThis study included 130 elderly patients who underwent LR for solitary treatment-naïve HCC between November 1998 and March 2020. Group 1 included patients who underwent LR before 2016 (n = 68) and group 2 included those who underwent LR during or after 2016 (n = 62).

resultsThe proportion of major LR, anatomical LR, and laparoscopic LR (LLR) in group 1 was significantly lower than those in group 2. Also, the median operation time, amount of blood loss, hospitalization length, rates of intraoperative blood transfusion, and complications in group 2 were less than those in group 1. In the subgroup analysis of group 1, high proteins induced by vitamin K absence or antagonist-II, long hospitalization, and LLR were closely associated with mortality. In the subgroup analysis of group 2, however, none of the factors increased mortality. Nevertheless, the presence of tumor grade 3 or 4 and the incidence of microvascular invasion were higher in group 1 than in group 2, and the disease-free survival and overall survival were better in group 2 than in group 1 because of minimized blood loss and quicker recovery period by increased surgical techniques and anatomical approach, and LLR.

conclusionLR in elderly HCC patients has been frequently performed recently, and the outcomes have improved significantly compared to the past.
