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

Only a few high-volume centers have reported the efficacy of laparoscopic liver resection (LLR) for patients with intrahepatic cholangiocarcinoma (ICC). The minimally invasive approach is still controversial for ICC, especially when dealing with large (≥5 cm) or multiple (≥2) ICCs.Patients with large and multiple ICCs who underwent LLR or open hepatectomy (OH) between January 2012 and June 2017 were included. Furthermore, 1:2 propensity score matching (PSM) was performed between the LLR group and the OH group. Short- and long-term outcomes were compared between the different techniques.After PSM, LLR resulted in significantly longer operation time (median 225 minutes vs 190 minutes, P = .006) and pringle maneuver time (median 50 minutes vs 32.5 minutes, P = .001). There was no statistically significant difference in postoperative hospital stay between the different approaches (median 6 days vs 7 days, P = .092). The grade III/IV complication rates were comparable between the groups (5.6% vs 11.1%, P = .868). In the PSM subset, there was no significant difference in terms of overall survival (P = .645) or disease-free survival (P = .827) between patients in the LLR group and in the OH group.The present study showed that patients who underwent LLR for large or multiple ICCs could obtain similar short- and long-term outcomes compared with those who underwent OH, and lymph node dissection (LND) was technically difficult but feasible during LLR.
