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

backgroundLaparoscopic surgery (LS) for hilar cholangiocarcinoma (HCCa) remains under development, and its feasibility and safety remain controversial. This study therefore evaluated the outcomes of this technique and compared them to those of open surgery (OS).

methodsIn total, 149 patients underwent surgical resection for HCCa at our center between February 2017 and September 2020. After screening and propensity score matching, 47 OS group patients and 20 LS group patients remained, and their baseline characteristics, pathologic findings, surgical outcomes, and long-term outcomes were compared.

resultThe baseline characteristics and pathologic findings were comparable between the two groups. The mean incision length was longer in the OS group than in the LS group (21.0 cm vs. 13.2 cm, P < 0.001). No significant differences were observed in the other surgical outcomes between the two groups. Regarding long-term outcomes, the overall survival rate and disease-free survival rate of the OS group were significantly higher than those of the LS group (P = 0.0057, P = 0.043). However, the two groups had significantly different follow-up times (19.2 months vs. 14.7 months, P = 0.041).

conclusionLS for HCCa is technically achievable, and our study revealed that it is equivalent to OS in terms of short-term outcomes but was poorer in terms of long-term outcomes.
