The interaction of the main exposure with gender was significant for MCS.
The interaction of the main exposure with gender was significant for SRH and MCS.
The interaction of the main exposure with age was significant for SRH.
For SRH, interactions of the main exposure with gender and age were significant.
In the linear RR models, one has the choice of combining additive terms for the main exposure with multiplicative terms for covariates, for example, RR = (1 + β1X1) × exp β2X2) × exp β3X3), where X2 and X3 represent covariates, or of using a strictly additive model for both covariates and exposure (e.g., RR = 1 + β1X1 + β2X2 + β3X3).
In the analyses for black tea, oolong tea, or coffee as a main exposure, persons with missing data were excluded (n = 11,449 for black tea, n = 12,883 for oolong tea, and n = 11,362 for coffee).
We conducted a logistic regression analysis with dependency (as defined by the modified Oxford handicap scale) as the outcome and haemorrhage growth as the main exposure variable, with adjustment by the potential confounders of initial haemorrhage volume, Glasgow coma scale, age, time from injury to computed tomography, and treatment.
All associations of the main exposure and outcome variables with socio-demographic and behavioural variables with a p-value < 0.1 are reported, as these variables were considered for inclusion in multivariate models.
In medieval Denmark the latter two must have been very rare, and we are left with main exposure ways either through medicine or through literary/academic work, both of which were mostly carried out in monastic environments [3].
21 Important differences in relation to our study include the mean age of the patients of 65 years (compared with 82 years in our study), the main exposure of medical conditions associated with a short length of stay, and the primary outcome (re-admission to hospital v mortality).
PAHs and silica have been suggested as main exposures associated with an increased risk in iron foundries, whereas PAHs, silica, chromium and nickel are implicated in steel foundries (Austin et al, 1997).
