Effect of progesterone intervention on the dynamic changes of AQP-4 in hypoxic-ischaemic brain damage.
Article in International journal of clinical and experimental medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
To observe the effect of progesterone (PROG) on blood-brain barrier (BBB) permeability, brain tissue water content and dynamic changes of aquaporin-4 (AQP-4) in neonatal rats with hypoxic-ischaemic brain damage (HIBD). 72 neonatal Wistar rats, aged 7 days old, were randomly divided into control, hypoxic-ischaemic (6, 24 and 72 h, and 7 d subgroups) and drug groups (6, 24 and 72 h, and 7 d subgroups). The HIBD animal model was established. BBB was detected via an Evans blue tracer. Brain water content was determined by the dry/wet method. The AQP-4 expression in the cerebral cortex was observed through immunohistochemistry and Western blot. BBB permeability in the cerebral cortex of the neonatal rats, brain water content and AQP-4 expression in the hypoxia-ischaemia group were significantly higher than those of the control group after hypoxia for 6 h (P < 0.05), continued to rise within 24 h and then reached the peak at 72 h. BBB permeability in the cerebral cortex of the neonatal rats, brain water content and AQP-4 expression in the drug group were significantly lower than those of the hypoxia-ischaemia group after hypoxia for 6, 24 and 72 h (P < 0.05). Moreover, BBB permeability and BBB expression were positively correlated with the AQP-4 expression. In conclusion, PROG protects the brain of HIBD neonatal rats by alleviating the damage of BBB and cerebral oedema. The protective effect of PROG may be related to the down-regulation of AQP-4 expression in the cerebral cortex of neonatal rats.
