Next we investigated the distribution of subjects' confidence ratings for our single-photon SPDC source.
Testing 23 different sets of strategy labels, we identify two sets that produce a distribution of subjects' choices which approximate the uniform distribution quite well.
Finally, the age distribution is represented in Fig. 7. Fig. 7 Age distribution histogram: the age distribution of subjects in the merged dataset is affected by a critical unbalancing.
The detailed distribution of subjects' gender and age groups in five-year intervals is shown in Fig. 2, and example images of subjects in our dataset are shown in Fig. 3.
This observation can be related to the larger sample size with equal distribution of subjects in each group of skeletal maturity stages in our study to maintain the purity of sample.
The distribution of subjects can be found in Table S5.
Table 2 shows the distribution of subjects according to each dimension of social capital.
Furthermore, because a previous study showed a significant functional difference of RR genotype in lymphocyte, we compared the distribution of subjects without or with Q allele.
Therefore, the association between judge ratings and the actual distribution of subjects into cases and controls was tested in the following way.
With regard to the age groupings for HBV epidemiology, the distribution of subjects in the ≤5 group was the same as that mentioned above.
This finding might be explained by the demographic factors of the study population, such as the gender and age distribution of subjects according to disease severity, but would need verification in future studies [45].
