^aAverage score at baseline corrected for clustering; ^bchange on outcome measure over 0, 6 and 20 weeks; ^ca negative estimate indicates decreases in the outcome for boys; ^da negative estimate indicates decreases in the outcome for every year older; *: statistically significant at α 0.01−0.05, **: statistically significant at α <0.01. Est, estimate; PTSD, posttraumatic stress disorder; SE, standard error.
