Prediction or interpretability?
Emerging Themes in Epidemiology - Tập 16 - Trang 1-3 - 2019
The journal published a review of the literature on recursive partition in
epidemiological research comparing two decision tree methods: classification and
regression trees (CARTs) and conditional inference trees (CITs). There are two
sources of potential confusion in the paper for readers: one lies in the
definition and the comparison of CITs and CARTs, while the other is more general
and it refe...
Assessing delivery practices of mothers over time and over space in Uganda, 2003–2012
Emerging Themes in Epidemiology - Tập 13 - Trang 1-12 - 2016
It is well known that safe delivery in a health facility reduces the risks of
maternal and infant mortality resulting from perinatal complications. What is
less understood are the factors associated with safe delivery practices. We
investigate factors influencing health facility delivery practices while
adjusting for multiple other factors simultaneously, spatial heterogeneity, and
trends over tim...
Non-differential measurement error does not always bias diagnostic likelihood ratios towards the null

Choosing a survey sample when data on the population are limited: a method using Global Positioning Systems and aerial and satellite photographs
Emerging Themes in Epidemiology - Tập 9 - Trang 1-7 - 2012
Various methods have been proposed for sampling when data on the population are
limited. However, these methods are often biased. We propose a new method to
draw a population sample using Global Positioning Systems and aerial or
satellite photographs. We randomly sampled Global Positioning System locations
in designated areas. A circle was drawn around each location with radius
representing 20 m. ...
Hard, harder, hardest: principal stratification, statistical identifiability, and the inherent difficulty of finding surrogate endpoints
Emerging Themes in Epidemiology - Tập 11 - Trang 1-11 - 2014
In many areas of clinical investigation there is great interest in identifying
and validating surrogate endpoints, biomarkers that can be measured a relatively
short time after a treatment has been administered and that can reliably predict
the effect of treatment on the clinical outcome of interest. However, despite
dramatic advances in the ability to measure biomarkers, the recent history of
cli...
Open access for the non-English-speaking world: overcoming the language barrier
Emerging Themes in Epidemiology - Tập 5 - Trang 1-6 - 2008
This editorial highlights the problem of language barrier in scientific
communication in spite of the recent success of Open Access Movement. Four
options for English-language journals to overcome the language barrier are
suggested: 1) abstracts in alternative languages provided by authors, 2) Wiki
open translation, 3) international board of translator-editors, and 4)
alternative language version ...
Testing bias in clinical databases: methodological considerations
Emerging Themes in Epidemiology - Tập 7 Số 1 - Trang 1-9 - 2010
Laboratory testing in clinical practice is never a random process. In this study
we evaluated testing bias for neutrophil counts in clinical practice by using
results from requested and non-requested hematological blood tests. This study
was conducted using data from the Utrecht Patient Oriented Database. This
clinical database is unique, as it contains physician requested data, but also
data that...
Challenges in modeling complexity of neglected tropical diseases: a review of dynamics of visceral leishmaniasis in resource limited settings
Emerging Themes in Epidemiology - Tập 14 - Trang 1-14 - 2017
Neglected tropical diseases (NTD), account for a large proportion of the global
disease burden, and their control faces several challenges including diminishing
human and financial resources for those distressed from such diseases. Visceral
leishmaniasis (VL), the second-largest parasitic killer (after malaria) and an
NTD affects poor populations and causes considerable cost to the affected
indivi...
Sib-recruitment for studying migration and its impact on obesity and diabetes
Emerging Themes in Epidemiology - Tập 3 - Trang 1-9 - 2006
Urban-rural comparisons are of limited relevance in examining the effects of
urban migration in developing countries where urbanisation is due to growth of
existing urban populations, expansion of urban boundaries, and rural
in-migration. Cultural, genetic and life-style backgrounds of migrants and host
populations further limit the value of rural-urban comparisons. Therefore we
evaluated a sib-co...
Assessing household wealth in health studies in developing countries: a comparison of participatory wealth ranking and survey techniques from rural South Africa
Emerging Themes in Epidemiology - Tập 4 - Trang 1-9 - 2007
Accurate tools for assessing household wealth are essential for many health
studies in developing countries. Household survey and participatory wealth
ranking (PWR) are two approaches to generate data for this purpose. A household
survey and PWR were conducted among eight villages in rural South Africa. We
developed three indicators of household wealth using the data. One indicator
used PWR data o...
