USE OF DECELLULARIZED HUMAN AMNIOTIC MEMBRANE IN INTESTINAL ANASTOMOSES: A STUDY IN RATS TREATED WITH 5-FLUOROURACIL.
Article in Arquivos brasileiros de cirurgia digestiva : ABCD = Brazilian archives of digestive surgery, 2024. 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
backgroundNowdays, more relevant applications of perinatal derivatives, such as amniotic membrane (AM), are emerging in our environment as a source of biomaterials for use in different healing processes. The study of anastomosis healing associated with antimetabolic drugs such as 5-fluorouracil (5-FU) is a potential target of AM.
aimsTo evaluate the healing effects of AM in rats treated with 5-FU at a dose of 20 mg/kg on the seventh day of postoperative evolution, regarding the parameters percentage of type I collagen (mature), cell viability, microvascular density and formation of granulation tissue.
methodsThirty-two Wistar rats were used, submitted to colotomy and colorraphy, separated into four groups of eight, which received different treatments daily, intraperitoneally, until the day of sacrifice: saline solution (C), 20 mg/kg 5-FU, 20 mg/kg 5-FU and AM.
resultsTreatment with 20 mg/kg of 5-FU, on the seventh postoperative day, induced adverse effects on the anastomotic healing process, evidenced by a decrease in the percentage of type I (mature) collagen, cell viability, microvascular density, fibrin-leukocyte scab formation and angiofibroblast proliferation; the use of AM under these conditions induced an improvement in the percentage of type I (mature) collagen.
conclusionsTreatment with 20 mg/kg of 5-FU on the seventh postoperative day induced adverse effects on the anastomotic healing process, and the use of AM under these conditions induced an improvement in the percentage of type I (mature) collagen.
