National utilization of minimally invasive and open liver resections.
Article in Surgical endoscopy, 2026. 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
introductionAlthough minimally invasive (MIS) liver resections are associated with improved outcomes, uptake remains slow.
methodsUsing data from the Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample (NIS), adults who underwent elective liver resections (2016-2020) were identified. Approach was classified as MIS (laparoscopic or robotic-assisted) or open. Annual utilization was characterized by approach and association between approach and patient and hospital variables was estimated.
resultsAmong 63,280 adult liver resections, 22.5% were MIS. MIS resections increased from 21.3% in 2016 to 22.5% in 2020. Laparoscopy alone decreased from 18.4 to 14.9%, while robotic-assistance increased from 2.9 to 7.6%. In multivariable analysis, patients were less likely to undergo MIS resection if they were in a county with < 250,000 people (vs. > 250,000, OR [95% CI], 0.82 [0.73-0.93]). Patients were more likely to undergo a MIS resection if they had a benign indication (vs. malignancy, OR [95% CI], 2.9 [2.49-3.38]), or were undergoing a partial hepatectomy (vs. lobectomy, OR, [95% CI], 2.62 [2.24-3.07]).
conclusionMIS liver resection increased between 2016 and 2020, driven by an increase in robotic-assisted surgery and despite a reduction in laparoscopic surgery. Rurality, indication, and resection type were contributors to a MIS vs. open approach.
