A range of potential confounders were available including tumour site, stage at diagnosis, grade of differentiation, place of presentation, specific symptoms and signs at presentation, type of admission (emergency or elective), age, gender, smoking status, Carstairs deprivation quintile and Charlson co-morbidity index (Charlson et al, 1987; Morris and Carstairs, 1991).
The place of presentation was distributed unevenly between the two emergency departments: 1152 (73.2%) patients presented to VGH, and 422 (26.8%) to SPH.
By stating in a sentence or two what you are going to talk about, you place your presentation into context.
After the baiting, E carried the board with the bowls on top to the place of presentation.
After the baiting, E carried the tubes to the place of presentation and positioned the tubes simultaneously on the ground/table, with a distance of approx. 50 cm between the tubes.
In model 2, age, smoking status, Carstairs deprivation quintile, Charlson co-morbidity index and place of presentation were included.
Symptoms and signs are complex, but, like emergency admission and place of presentation, are more likely to be markers of disease progression than intermediate variables.
For half of the place cells, presentation of the visual environment at the start of a run allowed place cells to fire in the correct location further along the track in terms of distance run on the ball.
Hence, adjustment for grade, symptoms and signs, emergency admissions and place of presentation was performed since they may be markers for the more biologically aggressive tumours believed to produce 'waiting time paradox' of poorest outcome for those with shortest delays (Neal, 2009).
We rounded all ORs and 95% CIs to the tenths place for presentation, and considered pesticide exposure to be "positively associated" with depression if the rounded lower 95% confidence limit for the OR was at least 1.0 or if the rounded OR was at least 1.3.
