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

Rats were implanted with cannulae in the CA1 area of the dorsal hippocampus and trained in one-trial step-down inhibitory avoidance. Two retention tests were carried out in each animal, one at 1.5 h to measure short-term memory (STM) and another at 24 h to measure long-term memory (LTM). The purpose of the present study was to evaluate the modulation on hippocampal nerve growth factor (NGF) and basic fibroblast growth factor (bFGF) on short- and long-term memory. Immediately after training, animals received 5 microl of NGF (0.05, 0.5 or 5.0 ng), bFGF (1.25, 12.5 or 125 ng) or saline per side. At the higher dose, NGF blocked STM. In contrast, NGF at dose of 0.5 and 5.0 ng improved LTM. The bFGF infusion at a dose of 125 ng enhanced LTM. However, bFGF did not alter STM. These findings indicate that hippocampal NGF and bFGF modulate STM and LTM in a different manner.
