Do existing research summaries on health systems match immunisation managers' needs in middle- and low-income countries?
Relevant, high quality research summaries were found for few of the topics identified by managers. Few proposals used national surveys evidence to identify barriers to vaccination. Researchers generating or adapting evidence about health systems need to be more responsive to managers' needs. Use of available evidence from local or national surveys should be strongly encouraged.
The results emphasize the strong relationship between floral longevity and pollination in orchids, as well as the influence of reproductive costs on the former.
