Can post-hoc video review of robotic pancreaticoduodenectomy predict portal/superior mesenteric vein margin status in pancreatic adenocarcinoma?
Observational study in HPB : the official journal of the International Hepato Pancreato Biliary Association, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundAchieving margin negative resection is a significant determinant of outcome in pancreatic adenocarcinoma (PDA). However, because of the fibrotic nature of PDA, it can be difficult to discriminate fibrosis from active disease intra-operatively. We sought to determine if post-hoc video review of robotic pancreatico-duodenectomy (RPD) could predict the portal/superior mesenteric vein (PV/SMV) margin status on final pathology.
methodsExperienced pancreatic surgeons, blinded to patient and operative variables, reviewed the PV/SMV margin for available RPD videos of consecutive PDA patients from 9/2012 through 6/2017.
results107 RPD videos were reviewed. Of 76 patients (71%) predicted to have a negative vein margin on video review, 20 patients (26%) had a pathologic positive margin. 25 of 31 patients (81%) predicted to have positive margin on video review were positive on pathology. The specificity of video prediction was 90.3% with a sensitivity of 55.6% and an accuracy of 75.7%.
conclusionPost-hoc video review prediction is unable to reliably predict a positive (R1) margin at the portal vein/SMV, suggesting that intra-operative clinical assessment may be suboptimal in determining the need for more extensive resections.
