Intranasal oxytocin in the treatment of autism spectrum disorders: A multilevel meta-analysis

Huang, Yi, Huang, Xin, Ebstein, Richard P., Yu, Rongjun·2021·Neuroscience & Biobehavioral Reviews

Abstract

Intranasal oxytocin has been shown to promote social functioning and has recently been applied as a treatment for autism spectrum disorders (ASD). The current meta-analysis aims to assess the crucial question of oxytocin's efficacy in the treatment of ASD. We performed a systematic literature search, including randomized, single- or double-blind/open-label and placebo-controlled clinical trials as well as single-arm, non-randomized and uncontrolled studies investigating exogenous oxytocin effect on ASD. A total of 28 studies (N = 726 ASD patients) met our predefined inclusion criteria. We used a multilevel meta-analytic model and found that oxytocin had beneficial effects on social functioning, but did not find strong evidence for symptoms improvement in the non-social domain. Our findings suggest that oxytocin administration can be regarded as an effective treatment for some core aspects of ASD, especially in the domain of social functioning, highlighting the promise of using oxytocin as a new-generation therapeutic to address core social impairments in ASD.

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?

  • The effects of OXT in ASD are likely modulated by age, gender, and possibly genetic factors.

    “It is also likely that the effects of OXT in ASD are modulated by age, gender, and possibly genetic factors [77, 79, 90].”
  • A recent meta-analysis suggests overall beneficial effects of OXT on social symptoms of ASD, although it included both children and adults.

    “Nonetheless, as illustrated by a recent meta-analysis, there does seem to be overall beneficial effects of OXT on social symptoms of ASD, although this review included both children and adults [90].”

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.
