Patient-reported outcomes of therapy with two brands of ibuprofen
Bibliographic record
Abstract
OBJECTIVE: To investigate patients' reported outcome following medication with two brands of 400 mg ibuprofen used to alleviate musculoskeletal pains. METHODS: Adult peasant manual laborers (85) who met criteria were randomly assigned to receive either of the brands (A or B). Data on pain alleviation were gathered using the Short-Form McGill Pain Questionnaire (SF-MPQ), Visual Analogue Scale (VAS), Present Pain Intensity (PPI), and Clinical Global Impression of Improvement (CGII) scales. Interval data obtained from the two brands were compared using the Students' t-test at 95% confidence interval. RESULTS: There were 42 participants, mean age=29.2 (SD=1.37) assigned to brand A and 43 (mean age=28.8 SD=1.14) in brand B of ibuprofen 400 mg. Brand B was consistently rated higher than brand A. Scores for medication efficacy were 10.4 (SD=1.65) (brand A) and 11.4 (SD=1.68) (brand B); t=2.768, P=0.007. Alleviation of pain symptoms: 10.8 (SD=1.64) and 11.6 (SD=1.72); t = 2.194, P=0.031. Similarly, rated scores on the impact of pain on quality of life were 10.5 (SD=2.00) and 12.1 (SD=1.85); t=3.830, P<0.001. There was a reduction in Present Pain Intensity scores by 32.7% and 34.3% for Brand A and brand B participants respectively. The decrease in Visual Analog pain scale score was 35.9% and 37.3% for brand A and brand B participants respectively. The decrease in SF-MPQ was by 85.1% and 69.9% for the brand A and brand B groups respectively. The clinical global impression of improvement for both groups of patients indicated an improvement rate of 71.4% and 61.9% for brand A and 81.4% and 74.4% for brand B participants. CONCLUSION: This clinical study infers that though the two brands of ibuprofen 400 mg are legally pharmaceutical equivalent, they are not clinically equivalent. In most of the parameters evaluated, brand B was rated more efficacious than brand A. This explains the patients' preferences and demand for this brand of ibuprofen in the Nigerian community.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
