Fig 1

Relationship between log10 transformed sample size and reported accuracy.

For 55 studies in the survey which applied ML methods in autism research. A: Relationship between log10 transformed sample size and accuracy, with a dark blue regression line and light blue area showing 95% confidence intervals. B: Classifiers used in the studies. C: Relationship between reported accuracy and log10 transformed sample size by year, bottom scatter-plots are for the studies published in that year. Year 2019 includes studies up to 18/04/2019 when the literature search was performed. N—sample size. D: Relationship between reported accuracy and log10 transformed sample size by modality of data used in the study.
