CSF 5-hydroxyindoleacetic Acid levels in suicidal schizophrenic patients

Abstract

Concentrations of 5-hydroxyindoleacetic acid (5-HIAA) in the lumbar CSF were measured in a group of suicidal schizophrenic patients and in a matched group of nonsuicidal schizophrenic patients. The suicidal group had a significantly lower level. This finding is consistent with reports of low levels of CSF 5-HIAA in suicidal patients with other psychiatric diagnoses and suggests that low CSF 5-HIAA may be a generalized marker of aggressive behavior against the self and others.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Reduced cerebrospinal fluid concentrations of 5-HIAA, the main serotonin metabolite, have been shown among suicide attempters, especially in those employing violent methods.

    “Biochemical studies have shown reduced cerebrospinal fluid (CSF) concentrations of 5-hydroxyindoleacetic acid (5-HIAA), the main serotonin metabolite, among suicide attempters, especially in those employing violent methods (23, 24).”

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.
