Sequential observations show upregulation of TGF-beta1 at the early phase of chronic small bowel rejection in rats.

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
Although TGF-beta1 is related to chronic rejection in various solid organs, its role remains controversial in the setting of small bowel transplantation. The aim of this study is to investigate the distinct role of TGF-beta1 and its receptors in the setting of chronic small bowel rejection. Sequential protocol biopsies were performed every 2 weeks from week 2 till week 8 after transplantation and recipients were sacrificed at week 16 as the end point. Gene expression was evaluated by SYBR Green I real-time polymerase chain reaction and protein was determined by immunohistochemistry. The gene expressions of TGF-beta1 and Type I receptor were upregulated and attained statistical significance at 4, 6 and 8 weeks in allografts. Dynamic expressions of TGF-beta1 and Type I receptor mRNA shown by sequential protocol biopsies support the view that TGF-beta1 signaling is involved in the pathogenesis of chronic small bowel rejection, especially at the early phase.
