SPATIAL MEMORY RECOVERY IN AGED MALE RATS TREATED WITH LEUPROLIDE ACETATE, A GNRH AGONIST.
Article in Acta endocrinologica (Bucharest, Romania : 2005). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Context: Studies indicate a decrease in spatial memory across species as they age. Moreover, consistent administration of Gonadotropin-releasing hormone (GnRH) improves learning abilities in older rats that have undergone gonadectomy. Objective: The aim of this study was to investigate the effects of the GnRH agonist, leuprolide acetate (LA) on spatial memory in aged intact male rats and the expression of proteins associated with hippocampal plasticity. Subjects and methods: Aged male rats were injected with LA or saline every three days for nine weeks to assess the effects of LA on spatial memory. The aged rats were trained in the Morris Water Maze for four days, and the evaluation took place on the fifth day. Additionally, the Y-maze test was used to investigate short-term spatial memory. The expression of spinophilin and microtubule-associated protein 2 (MAP2) in the hippocampus was measured. Results: Behavioral tests revealed that LA improves spatial memory in aged rats. Additionally, we observed increased expression of spinophilin and MAP2 in the hippocampus of aged male rats following LA treatment. Based on these results, the administration of LA holds is a potential treatment for restoring cognitive function in aged individuals.
