such as substations, underground cables, distribution or house wiring, or domestic appliances. This is a potential source of exposure misclassification for children whose addresses were not close to power lines. However, in another case–control study set in Britain, 2.3% of control children...
The purpose of this study was to explore the association between colds, depressive symptoms during pregnancy and offspring congenital heart disease (CHD). A 1:2 matching case-control study was conducted in Northwest China. Information was gathered by a structured questionnaire and was reviewed by in...
While writing case study assignment essays, students often face a number of problems that are often beyond their control. Making short and succinct case studies bearing relevant information and theoretical insights is not easy. Some typical issues faced by students are the following: ...
The aim of this study was to measure the amniotic fluid (AF) levels of EDCs and metals as well as the receptor transactivities induced by AF and investigate the possible link between prenatal exposure to EDCs and heavy metals and ASD risk. Methods In this case-control study, we included ...
Risk of stroke following herpes zoster: a self-controlled case-series study. Herpes zoster is common and vaccine preventable. Stroke risk may be increased following zoster, but evidence is sparse and could be explained by difference... M Sinéad,Langan,Caroline,... - 《Clinical Infectious Disease...
Here, we describe a whole-exome case-control study to evaluate the genic-level contribution of rare protein-coding variation to pancreatic cancer risk. We conduct gene-based tests to identify genes with an excess of rare, potentially damaging coding variation among cases, weighting each variant by...
We conducted a case-control study with 1416 women aged 18 years or older (705 cases, 711 controls). All participants underwent thyroid ultrasonography. Urinary total BPA (free and conjugated) concentration was quantified using the HPLC-MS/MS. We analyzed the association between urinary BPA conce...
In essence, this analysis used the cases from the case–control study, but extended the control set to consider the entire population of New Zealand. For both logistic regression analyses, ruminant livestock data from 2009 were used as they represented the most reliable recent data that could be...
In a US study, the risk of dying from sepsis was increased several 100-fold in ESRD patients as compared with the general population32. These findings could in part be explained by acquired immune deficiency due to uraemia as well as repetitive exposure of patients to potential infectious risk...
which explained 23%, 26%, and 8% of the observed heterogeneity in the allele contrast, dominant, and recessive genetic models, respectively. Similarly, the mean effect size of studies with more than 1000 control individuals was 0.1, 0.117, and 0.135 lower than studies with less than 1000 con...
