This illustrates current pitfalls in diagnosis and management of CKD. Advanced CKD requires renal function replacement by dialysis or transplantation. However, earlier CKD stages, even when renal function is still normal, are already associated with an increased risk of premature death (Perez-Gomez et al, 2019). Thus, novel approaches to diagnose and treat CKD are needed. The histopathological hallmark of CKD is kidney fibrosis, which is closely associated with local inflammation and loss of kidney parenchymal cells. Thus, kidney fibrosis is an attractive process to develop tests allowing an earlier diagnosis of CKD and represents a potential therapeutic target to slow CKD progression or promote regression. © 2020 The Authors.

Participants at Time 1 were 602 adults who reported directly experiencing a transportation accident within the past year (Mmonths = 6.36; SDmonths = 3.20). Of these participants, 171 adults completed the follow-up survey after 3 months (Time 2). Finite mixture modeling was conducted to identify the heterogeneity of PTSS in relation with PGI at each time point. At Time 1, a four-class model was the best-fitting model, and at Time 2, a three-class model was the best-fitting model. As hypothesized, when examined cross-sectionally, various subgroups were identified at each time point, finding subgroups with moderate to high levels of PGI but differing in their PTSS. However, when examining the longitudinal changes in class membership from Time 1 to Time 2, members of subgroups wi
