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

The hippocampal NMDA-receptor is predominantly involved to establish long-term potentiation (LTP) which is assumed to underlie fundamental molecular mechanisms of learning and memory. In the present study, NMDA-receptor density was investigated in parietotemporal cerebral cortex and in hippocampus of commonly bred naive adult male Wistar rats which had performed well or poorly in the passive avoidance paradigm. NMDA-receptor binding was determined in saturation experiments using (3H) MK-801 as a ligand and data for KD and Bmax were calculated from Scatchard plots. In general, higher NMDA receptor density was found in the hippocampus as compared to parietotemporal cerebral cortex. This regional difference became particularly obvious in good performers but was abolished in poor performers. In the hippocampus, a significantly higher NMDA-receptor density could be found in rats which had performed well in the passive avoidance task as compared to poor performers. In contrast, no such differences could be found in parietotemporal cerebral cortex. The data may indicate that the reduction in hippocampal NMDA-receptor density is of functional importance, for cognitive abilities in both physiological and pathophysiological conditions.
