Factor Analysis to Determine Subgroups of Gastrointestinal Symptoms in Systemic Sclerosis

J RheumatolPublished Cross-sectional study

Authors' conclusion

Despite the high correlation between GI manifestations, it is possible to detect subgroups of SSc-GI symptoms.

Study context

Population
Australian Scleroderma Cohort Study participants with systemic sclerosis (SSc) who completed the GIT 2.0 questionnaire
Participants
773 participants
Outcome
Latent factors (subgroups) of SSc-GI symptoms on factor analysis of GIT 2.0 domain scores and individual question responses
Methodological detailsfactor analysis, cluster analysis
  • Factor analysis
  • Cluster analysis

Main finding

As reported in the abstract

Latent factors of SSc-GI symptoms (individual GIT 2.0 question responses)
  • SSc-GI symptoms highly correlated
  • 4 latent factors: upper gastrointestinal (GI) tract symptoms, bloating, diarrhea and incontinence, and constipation

Observational data: associations, not effects.

Further findings

Patient clusters (cluster analysis)

2 patient clusters, distinguished by disease duration and severity of GI manifestations
Anticentromere antibodies and PAH more common in participants with severe GI disease
