Randomized Controlled Trial
Faster clean catch urine collection (Quick-Wee method) from infants: randomised controlled trial.
Objective To determine if a simple stimulation method increases the rate of infant voiding for clean catch urine within five minutes. Design Randomised controlled trial. Setting Emergency department of a tertiary paediatric hospital, Australia. ⋯ The number needed to treat was 4.7 (95% confidence interval 3.4 to 7.7) to successfully collect one additional urine sample within five minutes using Quick-Wee compared with standard clean catch urine. Conclusions Quick-Wee is a simple cutaneous stimulation method that significantly increases the five minute voiding and success rate of clean catch urine collection. Trial registration Australian New Zealand Clinical Trials Registry ACTRN12615000754549.

Objective To investigate whether the success rate of retrieving individual participant data (IPD) for use in IPD meta-analyses has increased over time, and to explore the characteristics associated with IPD retrieval. Design Systematic review of published IPD meta-analyses, supplemented by a reflection of the Cochrane Epilepsy Group's 20 years' experience of requesting IPD. Data sources Medline, CENTRAL, Scopus, Web of Science, CINAHL Plus, and PsycINFO. ⋯ There was no association between the source of funding of the IPD meta-analyses and IPD retrieval rate. The IPD retrieval rate of the Cochrane Epilepsy Group has declined from 83% (up to 2005) to 65% (between 2012 and 2015) and the reported reasons for lack of data availability have changed in recent years. Conclusions IPD meta-analyses are considered to be the "gold standard" for the synthesis of data from clinical research studies; however, only 25% of published IPD meta-analyses have had access to all IPD.
