Left censoring can occur with relative frequency when analyzing recurrent events in epidemiological studies, especially observational ones. Concretely, the inclusion of individuals that were already at risk before the effective initiation in a cohort study may cause the unawareness of prior episodes that have already been experienced, and this will easily lead to biased and inefficient estimates.

Background: Invasive pneumococcal disease due to serotype 3 (S3-IPD) is associated with high mortality rates and long-term adverse effects. The introduction of the 13-valent pneumococcal conjugate vaccine (PCV13) into the Spanish paediatric immunisation programme has not led to a decrease in the adult S3-IPD. [...]

21 p, 3.8 MB A critical trade-off between nitrogen quota and growth allows Coccolithus braarudii life cycle phases to exploit varying environment / de Vries, Joost (University of Bristol. Marine Biological Association) ; Monteiro, Fanny (University of Bristol) ; Langer, Gerald (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Brownlee, Colin (Marine Biological Association of the United Kingdom) ; Wheeler, Glen (The Marine Biological Association of the United Kingdom)
Coccolithophores have a distinct haplo-diplontic life cycle, which allows them to grow and divide into two different life cycle phases (haploid and diploid). These life cycle phases vary significantly in inorganic carbon content and morphology and inhabit distinct niches, with haploids generally preferring low-nitrogen and high-temperature and high-light environments in situ.
