Age-and-NSS associations in healthy and schizophrenia samples. (a) The overall relationship between age and NSSs in healthy and schizophrenia samples (n = 2315); (b) The relationship between age and NSSs in the healthy group (n = 1577); (c) the relationship between age and NSSs in the healthy group after matching the age range with the schizophrenia group (n = 1224); (d) the relationship between age and NSSs in schizophrenia group (n = 738). The transparent black dots are actual data points, with the less opacity representing more data points on certain values. The black solid lines represent the negative binomial regression predictions of the quadratic age effect on NSSs, and the surrounding broken red lines indicate 95% confidence intervals (CIs) of the estimations. NSS, neurological soft sign; OP, other psychiatric; SPD, schizotypal personality disorders.
