Agnita J.W. Boon, J. T. J. Tans, Ernst J. Delwel, Saskia M. Peerdeman, Patrick W. Hanlo, Hans A. L. Wurzer, C. J. J. Avezaat, Dirk A. de Jong et al.. Journal of neurosurgery, 1998-03-01
Topic: Brain imaging, connectivity and assessment
Outcome was better for patients who had an LPV shunt than for those with an MPV shunt, although most differences were not statistically significant. The authors advise that patients with NPH be treated with an LPV shunt.

Study details
- Evidence strengthHigh
How this study scored 45/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported and studied in people because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 26 of the 58 points we could judge it on, which is 45 out of 100.
