Table 1 TETHYS study flow diagram

From: PragmaTic, prospEctive, randomized, controlled, double-blind, mulTi-centre, multinational study on the safety and efficacy of a 6% HydroxYethyl Starch (HES) solution versus an electrolyte solution in trauma patients: study protocol for the TETHYS study

 

Time

Screening: at hospital admission

T0 (baseline): emergency room until IP treatment start

T1: First 24 h after IP treatment startb

T2: post-traumatic day 1b-3 (morning)

T3: post-traumatic day 4-7 (morning)

T4c: day 90 after randomization

  2. bIn case assessment of time points T1 and T2 (day 1) are within a timespan of max. 2 h only one assessment per variable has to be done to minimize intervention for the patient, otherwise deemed clinically required
  3. cA lag time of ± 14 days for the conduct of this follow-up contact is accepted, to account difficulties in obtaining data due to potential causes for delay (e.g., mail delay, or patient´s inability to travel)
  4. dexcept cystatin-C
