Figure F4 is a scatter diagram with regression line depicting associations between the time of followup and intermediate/ patient-centered outcomes, after electrical stimulation. The data came from 15 studies. The diagram has four graphs where the top-left graph is for disability, top-right for function composite, bottom-left for pain, and bottom-right for gait function. The x-axis is the time of followup and the y-axis is standardized effect size. All p-values of the correlation coefficients are greater than 0.05, except that of pain (p-value < 0.001). The results indicate that electrical stimulation improved pain at short followups but significantly worsened pain at longer follow-ups.
