This contrasts with non-population based studies such as hospital-based case series where sampling bias is a potentially major concern and the population at risk is rarely definable for community-onset disease [ 25].
In as far as there is some movement towards a more functionally-oriented approach in some T-G based studies, such as the analysis of English questions by Robert Fiengo (2007: 146, 170 1), there might now be something more of a move towards developing a consensus that both data and intuitions are needed.
This allows flux determination based solely on reaction stoichiometry and thermodynamics from the EMs generated by EMA, rather than applying a metabolic assumption (maximizing growth rate) in optimization based studies (such as FBA).
Also, the formula that was used for calculation of unmet need is one that is commonly used for community based surveys and was not designed for facility based studies such as ours.
While earlier studies have provided some important information, the ability of next generation sequencing based studies such as this to evaluate millions of bacterial sequences from diverse (and often unculturable) microbial populations is now possible.
Self-reported BMI although practical in population based studies such as the current study has well acknowledged limitations [ 43] therefore future studies are encouraged to use objective measures of body composition to confirm the pattern of results observed in the current study.
Since the included number of children is small, we are not able to compare this outcome to population based studies, such as the Bogalusa Heart study, which reported a positive family history for diabetes in 6% for normoglycaemic children and 9% for children with pre-diabetes [ 12].
Such a flaw is inevitable in questionnaire-based study such as this where environmental conditions remain same, and it is tempting for responders to associate such constant factors with an event as no objective parameter can be used.
There are clearly limitations to a retrospective, autopsy-based study such as the one we report here.
Discovering novel superfamily members in existing database sequences is one of the most important and exciting outcomes of a systematic computer-based study such as this.
A hospital-based study such as this will tend to underestimate the incidence of disease, and infections, such as scrub typhus, which tend to affect farmers, will be more common in rural Laos.
