Replication and reproducibility in spinal cord injury research
Abstract
This special issue of Experimental Neurology compiles a series of papers that either explicitly replicate published studies or retest phenomena reported in previous publications. The explicit replications were carried out as part of the "Facilities of Research Excellence-Spinal Cord Injury" (FORE-SCI) program launched by the National Institute of Neurological Disorders and Stroke (NINDS) in 2003. Here, we review the FORE-SCI replication experiments published prior to those in this special issue. We then discuss emerging issues regarding replication and reproducibility in spinal cord injury research, especially in terms of potential translation to clinical trials.

The low replication success rates and small effect sizes we found reinforce prior calls for improving rigor and transparency of preclinical research to improve allocation of limited resources and protect human participants from trials based on weak evidence.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
