Effects of long‑term scopolamine treatment on cognitive deficits and calcium binding proteins immunoreactivities in the mouse hippocampus.
Article in Molecular medicine reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
GABAergic projections terminate on numerous hippocampal interneurons containing calcium binding proteins (CBPs), including calbindin D‑28k (CB), calretinin (CR) and parvalbumin (PV). Memory deficits and expression levels of CB, CR, and PV were examined in the hippocampal subregions following systemic scopolamine (Scop; 1 mg/kg) treatment for 4 weeks in mice. Scop treatment induced significant memory deficits from 1 week after Scop treatment. CB, CR and PV immunoreactivities distributions were in hippocampal subregions [CA1 and CA3 regions, and the dentate gyrus (DG)]. CB immunoreactivity (CB+) was gradually decreased in all subregions until 2 weeks after Scop treatment, and CB+ was decreased to the lowest level in all subregions at 3 and 4 weeks. CR+ in the CA1 region was gradually decreased until 2 weeks and hardly observed at 3 and 4 weeks; in the CA3 region, CR+ was not altered in all subregions at any time. In the DG, CR+ was gradually decreased until 2 weeks and lowest at 3 and 4 weeks. PV+ in the CA1 region was not altered at 1 week, and gradually decreased from 2 weeks. In the CA3 region, PV+ did not change in any subregions at any time. In the DG, PV+ was not altered at 1 week, decreased at 2 weeks, and lowest at 3 and 4 weeks. In brief, Scop significantly decreased CBPs expressions in the hippocampus ≥3 weeks after the treatment although memory deficits had developed at 1 week. Therefore, it is suggested that Scop (1 mg/kg) must be systemically treated for ≥3 weeks to investigate changes in expression levels of CBPs in the hippocampus.
