Based on fair evidence, screening would result in no (or minimal) decrease in mortality from esophageal cancer in the U.S. population.

Description of the Evidence

  • Study Design: Evidence from cohort or case-control studies.
  • Internal Validity: Fair.
  • Consistency: Multiple studies.
  • Magnitude of Effects on Health Outcomes: Small positive.
  • External Validity: Poor.

Description of the Evidence

  • Study Design: Evidence obtained from cohort or case-control studies.
  • Internal Validity: Fair.
  • Consistency: Multiple studies, large number of participants.
  • Magnitude of Effects on Health Outcomes: Fair evidence for no reduction in mortality; good evidence for uncommon but serious harms.
  • External Validity: Poor.
