Impact of Surgeon Volume on Outcomes and Expenditure Among Medicare Beneficiaries Undergoing Liver Resection: the Effect of Minimally Invasive Surgery.
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
backgroundAlthough the role of annual surgeon volume on perioperative outcomes after liver resection (LR) has been investigated, there is a paucity of data regarding the impact of surgeon volume on outcomes of minimally invasive LR (MILR) versus open LR (OLR).
methodsPatients undergoing LR between 2013 and 2015 were identified in the Medicare inpatient Standard Analytic Files. Patients were classified into three groups based on surgeons' annual caseload: low (≤ 2 cases), medium (3-5 cases), or high (≥ 6 cases). Short-term outcomes and expenditures of LR, stratified by surgeon volume and minimally invasive surgery (MIS), were examined.
resultsAmong 3403 surgeons performing LR on 7169 patients, approximately 90% of surgeons performed less than 5 liver resections per year for Medicare patients. Only 7.1% of patients underwent MILR (n = 506). After adjustment, the likelihood of experiencing a complication and death within 90 days decreased with increasing surgeon volume. Outcomes of open and MILR among low- or high-volume surgeon groups, including rates of complications, 30- and 90-day readmission and mortality were similar. However, the difference of average total episode payment between open and MIS was higher in the high-volume surgeon group (low volume: $2929 vs. medium volume: $2333 vs. high volume: $7055).
conclusionAnnual surgeon volume was an important predictor of outcomes following LR. MILR had comparable results to open LR among both the low- and high-volume surgeons.
