Appendix 1. Search strategy for 2010 update

For this update we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 3), which includes the Cochrane Acute Respiratory Infections Group's Specialised Register; MEDLINE (1966 to Week 4, July 2010); EMBASE (1980 to August 2010); and CINAHL (1982 to August 2010).

For the previous update in 2007 we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 1) which includes the Cochrane Acute Respiratory Infections Group's Specialised Register; MEDLINE (1966 to March 2007); EMBASE (1980 to March 2007); and CINAHL (1982 to February 2007). MEDLINE, EMBASE and CINAHL were searched using OVID software. The MEDLINE search strategy is in Appendix 2.

The following search strategy was used to search MEDLINE and CENTRAL. The MEDLINE search was combined with the Cochrane Highly Sensitive Search Strategy for identifying randomised trials in MEDLINE: sensitivity‐ and precision‐maximising version (2008 revision); Ovid format (Lefebvre 2011). The search strategy was adapted to search Embase.com (see Appendix 3) and CINAHL (see Appendix 4).

*The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (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;

GRADE Working Group grades of evidence
High quality: Further research is very unlikely to change our confidence in the estimate of effect.
Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
Very low quality: We are very uncertain about the estimate.

1 No studies were found comparing different intravenous fluid regimens in adult populations in the systematic review.
2Duke 2002 and Singhi 1995 both have high risk of performance and detection bias, but this would not affect the mortality outcome. We did not downgrade in spite of the unclear risk of selection bias since it contributed to only 16.4% of weight and sensitivity analysis did not alter the effect estimates much. There was no risk of reporting bias for Singhi 1995 for the outcome of death.
3 The upper and lower limits of the 95% CI of the pooled estimate are very wide and thus indicate serious imprecision.
4 In Singhi 1995 selection bias was unclear and in both Duke 2002 and Singhi 1995 the performance and detection bias were at high risk. All this indicates very serious risk of bias for this outcome.
5 In Duke 2002 performance and detection bias were at high risk.
6 There was just one study so no downgrading was done for imprecision.
7Duke 2002 had a high risk of performance and detection bias which will cause serious risk of bias for evalulation of mild to moderate neurological sequelae.
