“Drag and drop” screening tool for eligibility checking in a sepsis trial with a narrow time window for enrolment. Each numbered bar represents a qualifying criterion. Whenever a criterion is recorded, the corresponding bar is dragged on the time line (blue). In fig. 2a, all the criteria were not recorded in the pre-specified window (P/F ratio recorded outside the time window). Thus, the patient cannot be included and the light is red. In fig. 2b, the light turned green as all criteria were recorded in the right time window and the time remaining for enrolment is indicated with the green bar. INR international normalized ratio, MAP mean arterial pressure, WBC white blood cells, PLT platelets, T temperature
