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

Vasoactive intestinal peptide (VIP) has been shown to be a potent promoter of neuronal survival. Pituitary adenylate cyclase-activating peptide (PACAP), a homologous peptide, shares activity and receptor molecules with VIP. The neuroprotective effects of VIP have been shown to be mediated via astroglial-derived molecules. Utilizing a battery of antisense oligodeoxynucleotides directed against the multiple cloned VIP-preferring (VIP receptors 1 and 2) or PACAP-preferring receptors (six splice variants derived from the same gene transcript), the authors have demonstrated the existence of a specific PACAP receptor splice variant (PACAP4 or hop2) on astrocytes as well as a VIP type2 receptor. The identification of the receptors was achieved by incubation of the cells in the presence of the specific antisense oligodeoxynucleotide followed by radiolabeled VIP binding and displacement. Polymerase chain reaction (PCR) coupled to direct sequencing identified the expression of the PACAP4-hop2 receptor splice variant in astrocytes. Neuronal survival assays were conducted in mixed neuronal-glial cultures derived from newborn rat cerebral cortex. When these cultures were exposed to the battery of the antisense oligodeoxynucleotides, in serum-free media, only the PACAP-specific ones (e.g., hop2-specific) had an effect in decreasing neuronal cell counts. Thus, the VIP neuronal survival effect is mediated, at least in part, via a specific PACAP receptor (containing a unique insertion of 27 amino acids--the hop2 cassette). These data indicate that a hop2-like PACAP/VIP receptor is the receptor that mediates neurotropism.
