Blinding?	Unclear	Not placebo controlled. No additional information provided.
All outcomes
Incomplete outcome data addressed?	Unclear	No losses or exclusions reported: analysis appears to be ITT
All outcomes
Free of selective reporting?	Unclear	Insufficient information to judge.
Free of other bias?	Unclear	There were no significant differences between the groups for risk factors for infection. There was insufficient other information which to judge
