Table 6 Overview of factors with strong evidence to be predictive of progression, overlap and differences between this review and the review of de Rooij et al., Wright et al., and Lievense et al.

From: Prognostic factors for progression of osteoarthritis of the hip: a systematic review

Prognostic factor Teirlinck et al. factor predictive of De Rooij et al. factor predictive of Wright et al. factor predictive of Lievense et al. factor predictive of
K-L grade at baseline THR Strong evidence for no association for clinical progression Radiological progression or THR* Not mentioned
Subchondral sclerosis at baseline THR Not mentioned Radiological progression and/or THR Not mentioned
Superior or (supero) lateral femoral head migration THR Not mentioned Radiological progression and/or THR Radiological progression and/or THR
Comorbidity Clinical progression Clinical progression (strong evidence for a course of function, weak evidence for a course of pain) Not mentioned Not mentioned
Low vitality Quality of life in general: strong evidence of no association, specific for SF 36 vitality: strong evidence for clinical progression Course of function Not mentioned Not mentioned
Age Conflicted evidence for THR and radiological progression, moderate evidence for no association with clinical progression Strong evidence for no association with pain and conflicted evidence for function Radiological progression and/or THR Conflicted evidence
Femoral osteophytes Conflicted evidence Not mentioned Radiological progression and/or THR Not mentioned
Hip pain at baseline Conflicted evidence Conflicted evidence Radiological progression and THR Not mentioned
JSW at baseline Conflicted evidence Not mentioned Radiological progression and/or THR Limited evidence for THR
Lequesne index score ≥ 10 at baseline Conflicted evidence for THR, moderate evidence for radiological progression** Conflicted evidence** Radiological progression and/or THR Not mentioned
Atrophic bone response Conflicted evidence Not mentioned Conflicted evidence Radiological progression
