С одной стороны "all filter recipients should be treated with indefinite anticoagulation regardless of their risk of recurrent thrombosis" - только не очень понятно что обозначает "(grade C, level IV)" - необязательность гипокоагуляции или относительная независимость от риска ТЭ?

в этом документе используется другая шкала уровня доказательности:

Classification of Evidence Levels

Ia Evidence obtained from meta-analysis of randomised controlled trials.

Ib Evidence obtained from at least one randomised controlled trial.

IIa Evidence obtained from at least one well-designed controlled study without randomisation.

IIb Evidence obtained from at least one other type of well-designed quasi-experimental study (refers to a situation in which implementation of an intervention is without the control of the investigators, but an opportunity exists to evaluate its effect).

III Evidence obtained from well-designed non-experimental descriptive studies, such as comparative studies, correlation studies and case studies.

IV Evidence obtained from expert committee reports or opinions and/or clinical experiences of respected authorities.

Classification of Grades of Recommendations

Grade A Requires at least one randomised controlled trial as part of a body of literature of overall good quality and consistency addressing specific recommendation (Evidence levels Ia, Ib).

Grade B Requires the availability of well conducted clinical studies but no randomised clinical trials on the topic of recommendation (Evidence levels IIa, IIb, III).

Grade C Requires evidence obtained from expert committee reports or opinions and/or clinical experiences of respected authorities. Indicates an absence of directly applicable clinical studies of good quality (Evidence level IV).
