In this issue of JAMA Pediatrics, Shaikh and colleagues1 report their analysis of risk factors for renal scarring in infants and young children following a urinary tract infection (UTI). The methods are notable. Shaikh and colleagues sought out individual patient data from multiple published articles, and the researchers of the original studies were generous enough to provide the data, resulting in a large data set of 1280 infants and children. This is an example of admirable collaboration among researchers, with clinicians and their patients the beneficiaries.
