Data are presented as means ± standard deviation or ratios (%). The paired test was used for analysis of continuous variables.

^*P < 0.05, before vs 1 month after the earthquake.

^**P < 0.05, before vs 3 months after the earthquake.

^†P < 0.05, 1 month vs 3 months after the earthquake.

BW, bodyweight; SBP, systolic blood pressure.
