Table 4 Comparison of effects of intervention on influenza vaccination of participants at two different stages

Period of time	Group	Total (n)	Number of vaccinations(n)	Vaccination rates(%)	χ²	P
Before intervention	the experimental group^a	769	223	29.0	0.934	0.334
Before intervention	the control group^b	769	206	26.8	0.934	0.334
After intervention	the experimental group	769	352	45.8	55.703	< 0.001
After intervention	the control group	769	211	27.4	55.703	< 0.001

^aBefore and after the intervention, the influenza vaccination rate of the experimental group was statistically different. (χ² = 43.432, P < 0.001). There was no significant difference in influenza vaccination rates in the control group after the intervention. (χ² = 0.082, P = 0.774)
