The First Mouse Model of Meckel's Diverticulum Carcinoma.
Article in In vivo (Athens, Greece). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundCancer of the Meckel's diverticulum (MD) is extremely rare. It is often advanced at the time of operation and the prognosis is poor. An effective treatment for this cancer has not yet been developed and there is no MD-carcinoma mouse model. MATERIALS AND
methodsMD carcinoma was established as a patient-derived xenograft (PDX) in 5-week-old male nude mice by subcutaneous transplantation of surgical specimens together with surrounding normal tissue. Hematoxylin and eosin (H&E) staining was performed on paraffin-embedded tissue sections of the original tumor resected from patients and transplanted tumors grown in nude mice.
resultsThree of five mice implanted with MD tumor fragments grew. MD-carcinoma histopathology, observed with H&E-stained tissue sections of the tumors grown in the mice and tumor from the original patient, was concordant. Both showed the luminal structures characteristic of MD carcinoma, and the lumens were filled with serous fluid.
conclusionThe first PDX mouse model of MD carcinoma has been established. The PDX model maintained MD-carcinoma histology of the tumor in the patient. The MD carcinoma mouse model will enable basic research on MD carcinoma, as well as the testing of novel therapeutic agents.
