Table 3 Purposively sampled t3 qualitative interviews (intervention arm) and their Impact Categorisation Levels

From: Is a specialist breathlessness service more effective and cost-effective for patients with advanced cancer and their carers than standard care? Findings of a mixed-method randomised controlled trial

Change in patient NRS distress due to breathlessnessa(primary outcome) t1 to t3 (and Impact Categorisation Level)
Cell 1: Biggest Improvers (from high baseline scores) Cell 2: Limited Improvers (high baseline score Cell 1 matches who improved the least)
533: NRS distress reduced from 8-1 (Level 2) 530: NRS distress reduced from 10-8 (Level 1)
564: NRS distress reduced from 7-1 (Level 1) 591: NRS distress: reduced from 10-8 (Level 1)
583: NRS distress reduced from 9-3 (Level 1) 624: NRS distress reduced from 10-8 (Level 2)
648: NRS distress reduced from 7-1 (Level 1) 536: NRS distress reduced from 5-3 (Level 1)
603: NRS distress reduced from 5-0 (Level 1) 630: NRS distress unchanged 4-4 (Level 2)
Cell 3: Worseners (who turned out to have a low-middling baseline scores) Cell 4: Moderate Improvers (closest baseline score Cell 3 matches who improved the most)
563: NRS distress increased from 4-9 (Level 2) 501: NRS distress reduced from 4-1 (Level 1)
578: NRS distress increased from 3-7 (Level 2) 637: NRS distress reduced from 3-0 (Level 3)
569: NRS distress increased from 5-7 (Level 1) 616: NRS distress reduced from 3-1 (Level 1)
612: NRS distress increased from 5-7 (Level 1) 658: NRS distress reduced from 8-4 (Level 2)
559: NRS distress increased from 5-6 (Level 2) 587: NRS distress reduced from 9-5 (Level 1)
  1. aHigh score is worse. Level 1 = significant impact; Level 2 = some impact; Level 3 = no impact. NRS, numerial rating score. Three-digit numbers = participant identity numbers.
