Please note: In 2003, the CTF updated its Grades of Recommendations to include an "I Recommendation" for situations where insufficient evidence exists to allow a recommendation to be made. (Formerly, these situations were captured under a "C Recommendation".) This change is not retroactive, and all "C Recommendations" made prior to 2003 have not been reevaluated in light of the new "I" recommendation grade. For a discussion of these recommendation grades, please link to the 2003 article in the Canadian Medical Association Journal here.
These recommendations were finalized by the Task Force in January 1994
| MANEUVER | EFFECTIVENESS | LEVEL OF EVIDENCE <REF> | RECOMMENDATION |
|
|
|||
| Clinical examination of postmenopausal women and measurement of serum thyroid-stimulating hormone (TSH) level by immunoradiometric assay. | Effectiveness of screening and early treatment has not been evaluated in the general population. | Community surveys <4-6> (III) | Poor evidence for either inclusion or exclusion of TSH screening (C); due to the high prevalence of thyroid disorders in peri-menopausal women, physicians should maintain a high index of clinical suspicion. |
| Early treatment of hypothyroidism may be beneficial for some women. | Randomized controlled trials <11,12> (I) | ||

| Neck palpation in asymptomatic adults. | Effectiveness of screening never evaluated. Poor test characteristics in asymptomatic adults. | Case-series <9,13> (III) | Poor evidence for either inclusion or exclusion of screening for thyroid cancer. (C) |
