Summary of findings 7. Procedures: Gloves with tab versus standard gloves.

Gloves with tab compared to standard gloves for preventing highly infectious diseases due to exposure to contaminated body fluids in healthcare staff
Patient or population: Preventing highly infectious diseases due to exposure to contaminated body fluids in healthcare staff Setting: Intervention: Gloves with tab Comparison: Standard gloves
Outcomes	Anticipated absolute effects* (95% CI)		Relative effect (95% CI)	№ of participants (studies)	Certainty of the evidence (GRADE)	Comments
	Risk with standard gloves	Risk with Gloves with tab
Any contamination of hands	Study population		OR 0.07 (0.04 to 0.12)	317 (1 RCT)	⊕⊝⊝⊝ VERY LOW 1 2
	733 per 1,000	161 per 1,000 (99 to 248)
*The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI: Confidence interval; RR: Risk ratio; OR: Odds ratio;
GRADE Working Group grades of evidence High certainty: We are very confident that the true effect lies close to that of the estimate of the effect Moderate certainty: We are moderately confident in the effect estimate: The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different Low certainty: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect Very low certainty: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect

¹ Clusters of health care workers who were present at work were allocated to intervention or control on alternating days and so we we downgraded with one level because of study limitations.

² This is a simulation study so we downgraded with one level because of indirectness.
