Four investigators (CC, LC, KL and KM) screened titles and abstracts for relevance in two phases based on the inclusion criteria: phase one eliminated all clearly irrelevant studies, phase two applied all inclusion/exclusion criteria listed above for the remaining studies.

We then tried to further bias the assay conditions by increasing the ATP concentration to 50-fold higher than KM and screening against the c-Src T338 M gatekeeper mutant.
Thus, the colonies that were resistant both to the higher temperature and two of the antibiotics (Amp and Cm, or Amp and Km) were screened for loss of resistance to the remaining antibiotic (Km or Cm) (Figure 2C, experiment series 2).
Subsequently, to evaluate substrate specificity at conditions where substrate cleavage velocities are proportional to kcat/ Km, we performed screening at a final substrate concentration of 1 μM, which was more than two times lower than the lowest established Km value.
Individual colonies were replicated in LB-Cm and LB-Cm-Km plates to screen for Km-sensitive colonies that have performed resolution of the cointegrant vector after I-SceI induction.
In multivariate analyses, non-participation was associated with older age, immigrant status, low OECD-adjusted household income, high and low level education compared with middle level education, unemployment, being unmarried, distance to screening site >20 km, being a tenant and no access to a vehicle.

Individual Km-sensitive colonies were screened by PCR with specific oligonucleotides to identify those with the desired modification in their chromosome (i.e., deletion, insertion, substitution).
As over one quarter of contacts in our study lived over 10 km from the screening clinic, consideration should to be given to a more decentralised approach to screening, particularly in rural areas.
