Graphical comparison of the calculated lesion volume depending on contact force for the very high-power short-duration (4 s) and the high-power short-duration protocol (4 and 15 s). The diagram illustrates the mean lesion volume for both the very high-power short-duration and high-power short-duration protocols in this study, depending on the applied contact force. The red line represents the data from the very high-power short-duration protocol (90 watts, 4 s), while the blue line corresponds to the high-power short-duration protocol (50 watts, 15 s).
