The impact of body mass index on short-term surgical outcomes after robotic liver surgery: a propensity-score matched analysis at a high-volume center in Denmark.
Article in Langenbeck's archives of surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSurgeons may experience technical complexity and negative outcomes related to robotic liver surgery (RLS) in obese patients. However, evidence regarding the impact of obesity on perioperative outcomes in RLS is limited.
methodsA retrospective analysis was performed on patients who underwent RLS between 2019 and 2024. Obesity was defined as a BMI ≥ 30 kg/m
resultsA total of 205 RLS procedures were performed at a high-volume hepatopancreatobiliary (HPB) center in Denmark. After 1:1 propensity score matching, 41 patients in each group were included. In the obese group, the rate of comorbid diabetes (p = 0.037) and the rate of steatosis (p = 0.035) were significantly higher in the obese group; standard liver volumes were also significantly larger (p < 0.001). There was no significant difference in the rate of major complications or the rate of all complications between the two groups. In multivariate binary logistic regression analysis using the nine factors selected in univariate analysis, only the IWATE criteria (≥ 7) showed a nearly significant p-value [p = 0.056], potentially suggesting an association with major postoperative complications.
conclusionsThe results of our single-center experience demonstrated that RLS in patients with a BMI of 30 or more did not impact postoperative surgical complications or other short-term outcomes. Therefore, RLS appears safe and feasible for obese patients in experienced centers.
