Near-zero open conversion rate of laparoscopic liver resection: a high-volume single-center experience of the past 5 years.
Article in Surgical endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundDespite widespread adoption and technological advances in laparoscopic liver resection (LLR), conversion to laparotomy can still occur unexpectedly. Several studies have explored risk factors of open conversion (OC). However, most of these studies were conducted before 2018 and included all patients who underwent surgery at an early stage after starting LLR. The purpose of this study was to analyze the incidence and risk factors of OC in patients within the past 5 years (2017-2021).
methodsPatients who underwent LLR at Samsung Medical Center from January 2017 to December 2021 were investigated. The incidence and causes of OC were investigated and risk factors associated with OC were also analyzed.
resultsA total of, 1951 patients were investigated. OC was observed in 34 patients (1.74%). The percentage of previous surgeries (50% vs. 25.5%, P < 0.001), history of hepatectomy (23.5% vs. 5.4%, P = 0.002), multi-focal disease (29.4% vs. 13.9%, P = 0.037), and posterosuperior (PS) location (64.7% vs. 39%, P = 0.004) were higher in the OC group. The most common cause of OC was adhesion (44.1%). In the analysis of risk factors associated with OC, PS location (OR 2.79, P = 0.007) and maximum tumor size (OR 0.92, P = 0.037) were statistically significant factors in multivariate analysis.
conclusionThe updated incidence of OC was 1.74%. The main cause of OC was adhesion. In addition, PS location and smaller tumor size were risk factors associated with OC.
