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

backgroundStandardization of surgical and pathologic techniques is crucial to the interpretation of studies evaluating adjuvant therapies for pancreatic cancer (PC).

methodsTo assess the degree to which treatment administered prior to enrollment of patients in trials of adjuvant therapy is quality controlled, the operative and pathology reports of patients in American College of Surgeons Oncology Group (ACOSOG) Z5031-a national trial of chemoradiation following pancreaticoduodenectomy (PD)-were rigorously evaluated. We analyzed variables with the potential to influence staging or outcome.

results80 patients reported to have undergone R0 (75%) or R1 (25%) pylorus-preserving (38%) or standard (62%) PD were evaluated. A search for metastases was documented in 96% of cases. The proximity of the tumor to the superior mesenteric vein was reported in 69%; vein resection was required in 9% and lateral venorrhaphy in 14%. The method of dissection along the superior mesenteric artery (SMA) was described in 68%, being ultrasonic dissection (17%), stapler (24%), and clamp and cut (59%). SMA skeletonization was described in 25%, and absence of disease following resection was documented in 24%. The surgeon reported marking the critical SMA margin in 25%; inking was documented in 65% of cases and evaluation of the SMA margin was reported in 47%. A range of 1-49 lymph nodes was evaluated. Only 34% of pathology reports met College of American Pathologists criteria.

conclusionsTrials of adjuvant therapy following PD suffer from a lack of standardization and quality control prior to patient enrollment. These data suggest areas for improvement in the design of multidisciplinary treatment protocols.
