A longitudinal study of autism spectrum disorders in individuals diagnosed with a developmental language disorder as children
Abstract
BACKGROUND: A number of studies have shown that the diagnosis of developmental language disorder (DLD) can be unstable over time, such that young children with a diagnosis of DLD may show symptoms more characteristics of autism spectrum disorder (ASD) at a later date. METHOD: To estimate the types and prevalence of ASD 469 individuals with a DLD, consecutively assessed in the same clinic during a period of 10 years, and 2345 controls from the general population were screened for ASD through the nationwide Danish Psychiatric Central Register (DPCR). The mean length of observation was 34.7 years, and the mean age at follow-up 35.8 (range: 28.3-46.7) years. RESULTS: At follow-up, 10 (2.1%) in the DLD group and two (0.09%) in the comparison group were known in the DPCR with a diagnosis of any ASD (P < 0.0001; odds ratio = 25.5; 95% confidence interval 5.5-116.9). CONCLUSION: Our results provide additional support to the notion that DLD is a marker of increased vulnerability to the development of ASD.

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.
