Association between ST2 level and GvHD risk
The average level of ST2 for all patients on day 14 was 39.48±17.78 and on day 28 was 37 ± 18.93. Given the these days ST2 level in patients and also based on previous studies in this area, a ST2 level of 33 ng/ml was used as the basis for measuring the difference in patients between high ST2 and low ST2 levels. The relationship between ST2 levels on day 14 and day 28 and onset of GvHD in patients was investigated. Of the 10 patients included in the study, 5 had grade II-IV GvHD. According to Table 9, the relation between GvHD and the standard deviation of ST2 in day 14 and 28 was parallel with the GvHD severity (Figure 6).
