Results of calculation of the RMSE between the estimated data and the ground truth data. Data were statistically compared with one another using Bonferroni correction. The significance levels were adjusted based on the number of groups (the three conditions) as follows: *p < 0.0167 (=0.05/3), **p < 0.0033 (=0.01/3). a Patient holding an empty bottle. b Patient holding a half-full bottle. c Patient holding a full bottle
