Determinants of Extraocular Muscle Volume in Patients with Graves' Disease

Table 2

Means ± SEM of measurements for patients with and without EOM volume enlargement. Where the measurement was not performed on all patients, the number of patients is shown in square brackets. 𝑃 values calculated using 2-sample t-test.
