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 olfactory ensheathing (glial) cells (OECs) have been identified to be useful candidate cells to support regeneration after being transplanted into injured fiber tracts of the central nervous system. We investigated by means of immunocytochemistry and freeze-fracturing the morphology and molecular composition of OEC tight junctions in the rat olfactory system. In addition, we tested the hypothesis whether tight junctions and orthogonal arrays of particles (OAPs) which contain the water channel protein aquaporin-4 (AQP4), are mutually exclusive as suggested in previous studies. In OECs, we found neither OAPs nor AQP4, but tight junctions immunoreactive for ZO-1, occludin, and claudin-5, but immunonegative for ZO-2 and claudin-3. To shed more light on the function of OEC tight junctions, we tested the permeability and tight junction composition of blood vessels and fila olfactoria. We found them both, permeable for infused lanthanum nitrate, and to be immunopositive for ZO-1 and claudin-5. The tight junctions of the OECs are discussed to be responsible for micro-compartmentalization within the olfactory fiber tract providing a benefit for axonal growth.
