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 microenvironment is a critical mediator of stem cell survival, proliferation, migration, and differentiation. The majority of preclinical studies involving transplantation of neural stem cells (NSCs) into the CNS have focused on injured or degenerating microenvironments, leaving a dearth of information as to how NSCs differentially respond to intact versus damaged CNS. Furthermore, single, terminal histological endpoints predominate, providing limited insight into the spatiotemporal dynamics of NSC engraftment and migration. We investigated the early and long-term engraftment dynamics of human CNS stem cells propagated as neurospheres (hCNS-SCns) following transplantation into uninjured versus subacutely injured spinal cords of immunodeficient NOD-scid mice. We stereologically quantified engraftment, survival, proliferation, migration, and differentiation at 1, 7, 14, 28, and 98 days posttransplantation, and identified injury-dependent alterations. Notably, the injured microenvironment decreased hCNS-SCns survival, delayed and altered the location of proliferation, influenced both total and fate-specific migration, and promoted oligodendrocyte maturation.
