Agreement (Bland & Altman) plot of the difference in microhardness (in HV values) (EXP–CTRL) against their mean average (experimental & control) for (a) the CaCl2 group and (b) the NaF group. Short-dash red line represents equality; Solid purple line represents the Mean difference in hardness; Dotted orange lines represent 95% CI limit; Black dash lines represent the limits of agreement (LOA) with 95% CI. In (a) one outlier positive value was found, while in (b) two outlier negative values were found.
