Comparison between clinical history method with Haigis formula and the remaining formulas (clinical history method with SRK/T, ; Modified-Masket formula, ; Barrett True K, ; Haigis-L, ; Shammas, ; and Barrett True K, ), where was considered statistically significant for multiple comparisons. Comparison between the remaining formulas ( for all comparisons).
SD = standard deviation.
