Statistics in medicine
Often in food safety and bio-surveillance it is desirable to estimate the probability that a contaminant or a function thereof exceeds an unsafe high threshold. The probability or chance in question is very small. To estimate such a probability, we need information about large values. In many cases, the data do not contain information about exceedi...

In testing for non-inferiority or superiority in a single arm study, the confidence interval of a single binomial proportion is frequently used. A number of such intervals are proposed in the literature and implemented in standard software packages. Unfortunately, use of different intervals leads to conflicting conclusions. Practitioners thus face ...

Massively parallel sequencing allows efficient determination of genomic sequences and intra-host polymorphisms for viruses. However, the sequencing depth that guarantees safe interpretation of the observed data is unclear. We demonstrated that 10-fold genome coverage may allow safe genome assembly, and 1000-fold coverage is required to obtain relia...
Review of Network Economics
The UK Government has proposed national roaming to ensure that consumers may use rival networks in areas where their own operator does not offer (network) coverage (these are known as partial not-spots). The proposed policy aimed at increasing the likelihood of callers being able to make and receive calls. While this may raise a number of concerns ...

Our study showed a rapid increasing VarV₂ coverage of children, indicating a growing acceptance of the 2-doses VarV schedule among children's caregivers and physicians after the new recommendation released. We highlighted the necessity for a 2-doses VarV vaccination school-entry requirement to achieve the high coverage of >90% and to eliminate disp...
Human vaccines & immunotherapeutics
Since the introduction of HPV vaccination programs in Canada in 2007, coverage has been below public health goals in many provinces and territories. This analysis investigated the determinants of HPV non-vaccination and vaccine refusal. Data from the Childhood National Immunization Coverage Survey (CNICS) 2013 were used to estimate the prevalence o...

Efforts to reduce screening inequalities appear to have resulted in a significant improvement in equitable delivery of breast screening, although not of cervical screening. More work is needed to understand the differences, and see whether broader lessons can be learned from the reduction of inequalities in breast screening participation.

Needle and syringe program (NSP) coverage is commonly used to assess NSP effectiveness. However, existing measures don't capture whether persons who inject drugs (PWIDs) stockpile syringes, an important and novel aspect of NSP coverage. In this study, we determine the extent of stockpiling in a sample of Australian PWIDs and assess whether includin...
Although there has been a positive development in overall palliative care coverage in Europe between 2005 and 2012, the services available in most countries are still insufficient to meet the palliative care needs of the population.
