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

Neurotrophins are key regulators of neuronal survival and function. Here we show that TrkB, the receptor for brain-derived neurotrophic factor (BDNF), is located at parallel fiber to Purkinje cell (PF/PC) synapses of the cerebellum. To determine the effects of TrkB receptor activation on synapse formation and function, we examined the parallel fiber to Purkinje cell synapses of mice with a targeted deletion of the BDNF gene. Although Purkinje cell dendrites are abnormal in BDNF -/- mice, PF/PC synapses are still able to form. Immunohistochemical analysis of mutant animals revealed the formation of numerous PF/PC synapses with the appropriate apposition of presynaptic and postsynaptic proteins. These synapses are functional, and no differences were detected in the waveform of evoked EPSCs, the amplitude of spontaneous mini-EPSCs, or the response to prolonged 10 Hz stimulus trains. However, paired-pulse facilitation, a form of short-term plasticity, is significantly decreased in BDNF -/- mice. Detailed ultrastructural analysis of the presynaptic terminals demonstrated that this change in synaptic function is accompanied by an increase in the total number of synaptic vesicles in mutant mice and a decrease in the proportion of vesicles that are docked. These data suggest that BDNF regulates both the mechanisms that underlie short-term synaptic plasticity and the steady-state relationship between different vesicle pools within the terminal.
