1 · What the graph read from 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.

2 · The registry

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

backgroundThe outcomes of minimally invasive pancreaticoduodenectomy have not been adequately compared with those of open pancreaticoduodenectomy in patients with pancreatic ductal adenocarcinoma. We performed a meta-analysis to compare the perioperative and oncological outcomes of these two pancreaticoduodenectomy procedures specifically in patients with pancreatic ductal adenocarcinoma.

methodsBefore this study was initiated, a specific protocol was designed and has been registered in PROSEPRO (ID: CRD42020149438). Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, PubMed, EMBASE, Web of Science, Cochrane Central Register, and ClinicalTrials.gov databases were systematically searched for studies published between January 1994 and October 2019. Overall survival, disease-free survival, and time to commencing adjuvant chemotherapy were the primary endpoint measurements, whereas perioperative and short-term outcomes were the secondary endpoints.

resultsThe final analysis included 9 retrospective cohorts comprising 11,242 patients (1377 who underwent minimally invasive pancreaticoduodenectomy and 9865 who underwent open pancreaticoduodenectomy). There were no significant differences in the patients' overall survival, operative time, postoperative complications, 30-day mortality, rate of vein resection, number of harvested lymph nodes, or rate of positive lymph nodes between the two approaches. However, disease-free survival, time to starting adjuvant chemotherapy, length of hospital stay, and rate of negative margins in patients who underwent minimally invasive pancreaticoduodenectomy showed improvements relative to those in patients who underwent open surgery.

conclusionsMinimally invasive pancreaticoduodenectomy provides similar or even improved perioperative, short-term, and long-term oncological outcomes when compared with open pancreaticoduodenectomy for patients with pancreatic ductal adenocarcinoma.
