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
backgroundColorectal cancer (CRC) is a major public health concern. Animal models play a crucial role in understanding the disease pathology and development of effective treatment strategies. Chemically induced CRC represents a cornerstone in animal model development; however, due to the presence of different animal species with different genetic backgrounds, it becomes mandatory to study the susceptibility of different mice species to CRC induction by different chemical entities such as 1,2-dimethylhydrazine (DMH). This study aimed to investigate the induction receptivity of two commonly used mice species, C57BL/6 and BALB/c, to DMH-induced CRC.
methodsBoth mice species were exposed to weekly intraperitoneal injections of DMH at a dose of 20 mg/kg body weight for 15 consecutive weeks. The response to DMH was evaluated by monitoring body weight gain, daily food intake, and gastrointestinal symptoms. At the end of exposure, histopathology of distal colon dissected from both species was analyzed.
resultsResults revealed that C57BL/6 had a higher response to DMH compared to BALB/c. A significant decrease in body weight gain concomitant with severe diarrhea was observed in C57BL/6 receiving DMH compared to their controls, without any difference in food intake. Histopathology of distal colon revealed aberrant crypt foci and loss of goblet cells in DMH-exposed C57BL/6 mice. On the other hand, BALB/c mice displayed a normal and intact colon, with a normal weight gain pattern, and without any gastrointestinal symptoms.
conclusionIn conclusion, C57BL/6 has a higher susceptibility toward chemical induction to CRC; therefore, it can be used to study CRC pathogenesis, prevention, and treatment.
