The effects of cell surface CD47 downregulation on ischaemia-reperfusion injury during pig liver transplantation.
Article in International journal of experimental pathology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
This study aimed to investigate the effect of cell surface CD47 downregulation on ischaemia-reperfusion injury (IRI) during pig liver transplantation. Blood samples were collected from healthy miniature Bama pigs randomly and equally divided into CD47 antagonism (group A), without CD47 antagonism (group B) and a sham group (group C). Blood samples were collected from groups A and B at 0, 8 and 48 hours after establishment of the new liver through an indwelling tube in the right internal jugular vein. Blood samples were collected at the same time points after liver dissociation from group C. The expression of interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) was detected by enzyme-linked immunosorbent assay (ELISA); CD47 expression was detected by Western blot; and liver function indices, including alanine aminotransferase (ALT) and aspartic transaminase (AST), were directly read by an automatic biochemical analyzer. The concentrations of both receptors in group A were significantly lower than groups B and C, at 8 and 48 hours after establishment of blood flow. At 8 and 48 hours in the new liver stage, the values of CD47 levels, ALT and AST in group A were significantly reduced compared to groups B and C (P < 0.05). The levels of CD47 in the three groups were consistent with the trends of the aforementioned observation indicators. The liver functions of the recipients were significantly improved by reducing the release of the inflammatory mediators. This study provides new ideas and intervention approaches for the treatment of IRI in liver transplantation.
