Akt activator SC79 prevents impaired subsequent LTP in the hippocampus of hypothyroid 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
This study, investigated whether impaired hippocampal subsequent LTP due to hypothyroidism could be prevented by the Akt activator SC79. Hypothyroidism was induced by PTU (% 0.05) by giving it in drinking water for 21 days. Hippocampal subsequent LTP was induced by HFS (4 × 100 Hz) followed by LFS (5 Hz, 900 pulses, three min.). SC79 or saline was infused intrahippocampally for one hour, starting from induction of subsequent LTP. LTP was evaluated as field excitatory postsynaptic potential (fEPSP) slope and population spike (PS) amplitude. It was found that both the fEPSP slope and PS amplitude of the hypothyroid group rats were significantly reduced compared to the control, control + SC79, and hypothyroidism + SC79 infusion group rats. These findings indicate that hypothyroidism reduces hippocampal subsequent LTP in young-adult rats, while the infusion of the Akt activator SC79 prevents this decrease. Thus, decreased activation of Akt is responsible for the impaired hippocampal subsequent LTP in hypothyroidism.
