A systematic review of the effectiveness of antimicrobial rinse-free hand sanitizers for prevention of illness-related absenteeism in elementary school children

Table 3 Absences due to communicable illness, person-time incidence rates and percent relative effects of a non-alcoholic rinse-free hand sanitizer

			Intervention		Control
Trials		No. of students	No. of absences (no. of student-days)	Absenteeism rate per 100 student-days	No. of absences (no. of student-days)	Absenteeism rate per 100 student-days	Percent Relative Effect (95% CI)*
White et al. ⁴¹		770	153 (9615)	1.59	222 (9459)	2.35	33 (17, 45)
Dyer et al. ²⁷	Phase 1	420	70 (4136)	1.69	105 (4120)	2.55	34 (10, 50)
	Phase 2	420	28 (4156)	0.674	63 (4140)	1.52	56 (31, 72)

* Percent relative effect = (1- intervention rate/control rate)*100
95 percent confidence interval = (1–95% UCL of Rate Ratio)*100 to (1–95% LCL of Rate Ratio)*100
