"Bivalves can live in saltwater or freshwater and biologically, clams can live in different regions as they only need a stratum of sand or clay," he says.
Under the assumption of no interaction between the modifiable and non-modifiable risk factors of interest, the partial PAR is formulated as where t denotes a stratum of unique combinations of levels of all background risk factors which are not modifiable and/or not under study, t=1,…, T and OR2 t is the odds ratio in combination t relative to the lowest risk level, where OR2,1=1.
Methods and Results One hundred ninety-three patients with symptomatic PSVT were enrolled in 4 double-blind, randomized, placebo-controlled clinical trials with almost identical trial design (supraventricular arrhythmia-1 [SVA-1], SVA-2, SVA-3, and SVA-4), performed as a separate stratum of studies that also included a stratum of patients with atrial fibrillation or flutter.
The treatment assignment was also included as a stratum (because of the interaction between treatment and MGMT methylation).
As a result a strata of our society that might have saved David Bernstein the ignominy of having to pretend he had a long list of candidates for the England job by waving about a bit of paper with last night's takeaway order scribbled on it has dropped through the net leaving us to clutch at well‑thatched straws such as Aidy Boothroyd and Steve Bruce.
Figure 12 Context as a higher stratum of meaning (an SFL perspective).
The relation between language and context is more naturally imaged in SFL terms as Figure 12 below, with context privileged as a higher stratum of meaning (cf. Halliday 2002/2005b for a clear articulation of this position).
The supervenient perspective was the one just introduced, whereby context is treated as a higher stratum of meaning; the circumvenient one would alternatively see language as embedded in social context, where social context is interpreted as extra-linguistic.
It is immediately, pre-reflectively, and non-inferentially given or present as a founding stratum of our experiential life.
We considered each regional health administration as a stratum and randomly selected a proportion of the primary healthcare units for each regional administration.
