Mapping of local recurrence after pancreaticoduodenectomy for distal extrahepatic cholangiocarcinoma: implications for adjuvant radiotherapy.
Article in The British journal of radiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
objectiveTo generate a map of local recurrences after pancreaticoduodenectomy (PD) for patients with distal extrahepatic cholangiocarcinoma (DEHC) and to evaluate the adequate target volume coverage encompassing the majority of local recurrences when the clinical target volume (CTV) for pancreatic cancer was applied.
methodsWe retrospectively reviewed the records of DEHC patients who underwent pancreaticoduodenectomy and had postoperative CT scans acquired between 1991 and 2015 available. The sites of local recurrence were delineated on individual CT scans, and then, mapping was manually performed onto template CT images. Coverage of each site of local recurrence was evaluated by applying the CTV defined according to Radiation Therapy Oncology Group (RTOG) consensus guidelines (CTV
resultsOf the 99 patients, 36 patients had a total of 62 local relapses identifiable by postoperative CT scans; the relapses were the most frequent in the choledochojejunostomy (CJ) site, 11 sites (17.7%); para-aortic area, 10 sites (16.1%), superior mesenteric artery area, 10 sites (16.1%); and portal vein area, 9 sites (14.5%). 21 sites (33.9%) were not covered by the CTV
conclusionWhen mapping of local relapses was evaluated according to the CTV ADVANCES IN KNOWLEDGE: Mapping local recurrences can aid in defining appropriate target volume for postoperative radiotherapy in DEHC.
