Then, we considered each domain rated as unclear as missing data and used multiple imputations to attribute a risk-of-bias assessment of high or low to these domains.
29 30 Based on this model, an isolated risk factor of sepsis would attribute a low risk of venous thromboembolism (around 0.7%).
Indeed, inherent covariates make it difficult to attribute an increased risk of fractures to GC usage in our study, e.g. patients with morphometric vertebral fractures had a statistically significantly longer time since menopause than patients with an absence of these fractures.
A model including data from RASP 107 increased the information size to 87.9% when attributed a relative risk of 0.9, resulting in the cumulative z score touching the conventional boundary of benefit (P=0.05) but not the trial sequential monitoring boundary of benefit (corrected 95% confidence interval 0.85 to 1.02; D=0%) (online supplement).
All insignificant lesions were attributed a low-risk classification when applying our biopsy risk stratification criteria.
When applying biopsy risk stratification criteria (≥6 mm MCCL and/or ≥50% positive cores) (Table 1), the 12-core TRUS biopsy correctly attributed a high-risk classification to 24% (20 of 85) clinically significant cases.
The impact of increasing the error was evaluated (Fig. 1), as well as the proportion of detected cases that were attributed a high-risk status (based on biopsy parameters) by each biopsy strategy (Table 1).
Given the widespread nature of low-moderate drinking water iAs contamination and a 12-14% baseline incidence of spontaneous clinical pregnancy loss in humans [ 23, 24], even a modest increase in risk will attribute a large number of events and thus comprise a substantial public health burden.
Case-control studies tend to overestimate odds ratios and this may be related to selection bias (most likely the case in the example above) or information bias (patients may attribute a disease to a known risk factor and they over-report this exposure).
The proportion of cancers in the total population that can be attributed to a risk factor is called the population attributable fraction (PAF), and corresponds to the proportional reduction in the population disease or mortality that would occur if exposure to the risk factor was modified according to an alternative exposure scenario.
Systemic complement activation is associated with age-related macular degeneration (AMD) and has mainly been attributed to a risk allele in the complement factor H (CFH) gene.
