Study selection (also known as screening) is the process by which records identified in the search are assessed for inclusion. Objectively and systematically applying the pre-specified eligibility criteria to each record in order to determine whether the article should be included helps avoid selection bias.
Take note on the following points before screening search results:
‣Title and abstract screening:
Each reviewer will need to read titles and abstracts of the papers to see if they match the inclusion & exclusion criteria. This is done separately by each reviewer. After both reviewers have evaluated the studies, votes are compared.
In the second round of screening, members evaluate the remaining studies by reading the full-text articles. Members must record the reasons for excluding studies based on the pre-determined inclusion & exclusion criteria.
To prevent bias, study selection is completed by two independent reviewers with a third person available for resolving conflicts. Alternatively, disagreement of study selection may be resolved by discussion between the reviewers.

When this is still not enough, you can see if your institution can borrow the article from other libraries via the Inter-library loans (ILL) program against a small fee. It should be reported if a full-text cannot be obtained.
For every article from which the full-text is screened, a reason should be listed for inclusion or exclusion.
