Swimmer plot. The x-axis represents time since the introduction of TPO-RAs, measured in months and the y-axis shows each of the 28 patient’s individual treatment courses. Colors are used to indicate different responses: the gray color denotes absence of response or insufficient response (with the use of immunosuppressants for an ITP relapse); the green color indicates a response or complete response to TPO-RAs, with the treatment ongoing; and the green/grey color represents a response or complete response to TPO-RAs, after discontinuation of treatment. Hourglass symbols: orange, immunosuppressants used concomitantly to TPO-RAs; red, time at which immunosuppressants were introduced for an ITP relapse; and purple, time at which immunosuppressants were introduced for other medical reasons. Lines represent time when TPO-RAs were discontinued.
