Quality rather than outcome should be the measure on which a publication decision is made; commercial bias may further complicate this balance. Lower IF-rated journals may serve a decidedly useful purpose by publishing more negative and inconclusive outcome studies. The practice of focusing disproportionately on the positive outcomes of most studies may result in unbalanced evidence.
Olympus cystoscopes require repair every 2 to 3 years and they appear to be durable. The distal deflection tip, specifically the outer bending rubber, is the most common site of flexible cystoscope damage. Although it appears that significant improvements have been made to the deflection apparatus, the number of repairs to other areas has not changed significantly with time. Improvements in form and function of the distal tip, the hand control segment and the fiberoptic bundles may enhance the durability of flexible cystoscopes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
