Dear Authors,
Recently, the work “Urban-rural differences in factors associated with willingness to receive eldercare among the elderly: a cross-sectional survey in China”[1] was published in BMJ Open, it discussed the influencing factors of the eldercare model, and I had the pleasure to enjoy it. But I have a question that in the ninth paragraph in introduction section: “Many other recent studies have examined differences in willingness to receive eldercare between urban and rural areas.” But, there is not a reference, indicating the “many”? Biomedical research waste [2,3] is heatedly discussed recently, and “Towards evidence based research” [4] was published in BMJ and it pointed out that all new research should be based on existing evidence. So, should there be a relevant reference?
