The effect of peer education based on adolescent health education on the resilience of children and adolescents: A cluster randomized controlled trial

Table 2. (Continued) Characteristics Control (n = 669) Intervention (n = 669) P Age 12.34±1.64 12.39±1.51 0.643b a P values were calculated using the chi-square test. b P values were calculated using the rank sum test. Quantitative data were expressed by “mean ± standard deviation”, while qualitative data were expressed by “n (%)”. https://doi.org/10.1371/journal.pone.0263012.t002 Table 3.
