What the research actually shows
NCT01048866 randomized 198 adults, 101 versus 97, to flurbiprofen 8.75 mg or a sugar-based placebo lozenge every 3-6 hours, up to five in 24 hours. The primary endpoint was 24-hour time-weighted SPID; 194 participants were evaluable. Two-hour swallowing-difficulty sums were -37.1 (SD 39.60) versus -18.1 (SD 29.43). The study belonged to the Reckitt Benckiser Healthcare International development program.
Why this is classified as C (46)
Patient-reported pain improved, but magnitude was about 0.45 SD and the small evidence base was manufacturer-only, giving C with 46 points. Follow-up was appropriate for acute sore throat.
Counterpoint. C does not mean no analgesic action; it marks limited independence, duration, size, and clinical interpretability.
Rejudgment record. Cross-check applied — Placebo-lozenge comparison, 24-hour SPID, Cohen's statistical magnitude convention, manufacturer funding, and small trials
| Endpoint | P | Patient-reported treatment goal - the symptom is the goal |
| Replication | R1 | Single confirmatory trial |
| Independence | I0 | Evidence comes only from manufacturer studies |
| Effect size | E~ | Statistically positive but below the threshold |
