All relevant titles and abstracts were screened (level 1).
At the abstract screening level, 1100 citations were excluded for the following reasons: prevalence of schizophrenia not reported (n = 802), study type (n = 238), and not a sample from the general population (n = 60).
A final screening (level 3) excluded reports describing clinical practice guidelines, systematic reviews, and commentaries/editorials that had initially passed into data abstraction before the project scope was narrowed to exclude examination of the strength of the empirical evidence supporting any given recommended breast cancer care.
Specifically, concentrations of BDE 47, BDE 99, TCEP, TDCIPP, BB 153, and DDT exceed screening levels, with 13 of 16 homes exceeding at least one chemical screening level in either sampling round.
Disagreements arising at screening levels 2 or 3 were resolved by forced consensus and, if necessary, third party intervention.
At full paper screen level, 33 out of 380 papers required review by a third party due to conflict between the first and second reviewer.
Thus, when all methods were considered, screening levels reached 98% (169/172 subjects).
Two reviewers will independently screen the titles and abstracts identified by the literature search for inclusion using the screening form (level 1 screening).
The reference monitoring wells with their latitude, longitude and screen level elevations were assigned at 3-D nodes of the finite element mesh.
The first (cut off 10) representing a screening level [ 50] and the second (cut off 13) supposed to catch more severe clinical depressive symptomatology [ 56].
