Figure 3.

Bar graphs comparing reading parameters between early-stage Parkinson's disease (PD) patients and healthy controls. Graph A shows various reading metrics like text read percentages, saccade velocity, and fixation numbers, with notable differences in the percentage of read text before stopping and saccade ratios. Graph B highlights eye fixation parameters, with significant differences in the duration of eye fixation. P-values indicate statistical significance. Early-stage PD is represented in blue, healthy controls in orange. Error bars show standard errors.

(A) Comparison of reading test parameters between patients with early-stage PD and healthy controls. (B) Comparison of parameters of eye fixation during reading test between patients with early-stage PD and healthy controls.
