Systemic levels of timolol by dose/body weight and by wound type. (A) The administered timolol dose per kg body weight plotted against the systemic plasma timolol level. Linear regression analysis of the data: R-squared, fitness of the data to the regression line is 0.47 in the chronic wound group and 0.01 in the glaucoma group. (B) The mean plasma level of timolol in patients in each category of wound was tallied. The difference in group means is not statistically significant.
