1 · What the graph read from it

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.

2 · The registry

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

Calcitriol can promote random pattern flap survival and increase autophagy activity. However, effect of autophagy on flap survival after calcitriol treatment, along with the underlying mechanism, is undefined. In this study, the "McFarlane flap" model was established in 72 rats divided into control, calcitriol, and calcitriol+3-methyladenine (3MA) groups and injected with saline, calcitriol, and calcitriol plus 3MA, respectively. The percentage flap survival area and tissue water content were tested after 7 days. The extent of autophagy was evaluated by the expression of the autophagy markers LC3-II/I, Beclin1, and p62. Flap angiogenesis was assessed via hematoxylin and eosin (H&E) staining and immunohistochemistry (for CD34 levels). The level of vascular endothelial growth factor (VEGF) protein/mRNA was measured. Oxidative stress was assessed by measuring the activity of tissue superoxide dismutase (SOD) and the contents of glutathione (GSH) and malondialdehyde (MDA). Our results showed that 3MA decreased autophagy in random skin flap treated with calcitriol. Compared with the calcitriol group, the calcitriol+3MA group showed a smaller mean flap survival area and greater tissue edema, had a markedly decreased level of VEGF mRNA/protein and SOD activity, and a significantly higher level of MDA and GSH. H&E staining and immunohistochemistry showed that angiogenesis was inhibited in this group. In conclusion, calcitriol increased angiogenesis and reduced oxidative stress via activation of autophagy, contributing to a significant increase in random skin flap survival.
