Life-table analysis: cumulative survival rate by sex at 5 years. Men (n = 170), 57%; women (n = 42), 86%. No statistical difference demonstrated (p = 0.66).

3. Fig. 2
Life-table analysis: cumulative stroke-free and transient ischemic attack (TIA)—free rates. Five-year cumulative rates were as follows: all strokes, 75%; ipsilateral strokes, 84%; all TIAs, 81%; ipsilaterial TIAs, 91%. Closed circles, stroke; open triangles, TIA.

4. Fig. 3
Life-table analysis: cumulative survival by severity of contralateral disease (percentage of vessel diameter reduction). A, normal (n = 2); B, 1% to 15% (n = 50); C, 16% to 49% (n = 53); D, 50% to 99% (n = 98); and E, occluded (n = 8). Statistical significance demonstrated (p = 0.04).

5. Fig. 4
Life-table analysis: cumulative stroke-free rate for hemisphere ipsilateral to the patent carotid artery grouped by severity of disease in that artery. For explanation of categories, see Fig. 3. No statistical significance demonstrated (p = 0.73).

6. Fig. 5
Life-table analysis: cumulative survival for patients with and without endarterectomy (TEA). Operated group (TEA +): n = 155, n = 108, n = 84, n = 46, and n = 24 at 1, 2, 3, 4, and 5 years, respectively. Nonoperated group (TEA −): n = 55, n = 46, n = 33, n = 20, and n = 15 at 1, 2, 3, 4, and 5 years, respectively.
