Table 3

Duration of operation (min) for class of length of incision, stratified by class of thyroid volume (ml)
Length < 1 st.dev (<4.5) Length ± 1 st.dev (m: 5.2 ± 0.7) Length > 1 st.dev. (>5.9)
Volume < 1 st.dev. (<10. 5 ml) 78.75 ± 17.9 90.0 ± 8.66
Volume ± 1 st.dev. (m: 33.26 ± 22.65) 92.66 ± 18.21 101.66 ± 21.0 105.83 ± 23.14
Volume > 1 st.dev. (>56 ml) 106.0 ± 36.8 106.87 ± 22.0

(mean ± st.dev.)

ANOVA: differences in duration of operation for each stratum of volume were not significant.
