“…Differences in the PTA incidence in individual periods of the year (spring, summer, autumn, and winter) are not significant in our group (p = 0.4396), nor were they significant in studies from Denmark, England, or the USA [13,23,37].

In our work, a detailed analysis revealed that the incidence of PTA in boys in group I (0-18 years) is statistically significantly higher during the summer and, conversely, is at its lowest in the autumn (p = 0.0023).…”
