Interchangeability of the EQ-5D and the SF-6D, and comparison of their psychometric properties in a spinal postoperative Spanish population.
Article in The European journal of health economics : HEPAC : health economics in prevention and care, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveEuroQol-5D (EQ-5D) and Short-Form Six-Dimensions (SF-6D) are widely used to calculate quality-adjusted life-years in cost-utility analysis. The choice of the instrument could influence the results of cost-utility analysis. Our objective was to compare the psychometric properties of the EQ-5D and SF-6D in a postoperative Spanish population, as well as assess their interchangeability in a cost-utility analysis.
designAmbispective study.
settingTertiary public hospital.
participants275 Spanish patients who had undergone surgery for lumbar disc herniation. INTERVENTION(S): Patients completed EQ-5D-3L and Short-Form 36 (SF-36v2) questionnaires. Internal consistency, floor and ceiling effects, agreement, and construct validity (convergent validity, including dimension-to-dimension correlations, and "known groups" validity) were assessed. The Spanish tariffs were applied. MAIN OUTCOME MEASURE(S): Cronbach's α coefficient, Spearman's rank correlation coefficient, Lin's concordance correlation coefficient, intraclass correlation coefficient and Bland-Altman plot.
resultsMain findings were: (a) lack of agreement between EQ-5D and SF-6D utilities (Lin's concordance correlation coefficient: 0.664 [95% CI: 0.600-0.720]; the Bland-Altman plot showed a mean difference of 0.0835 and wide limits of agreement [- 0.2602-0.4272]). (b) Lack of correlation between domains that theoretically measure similar aspects of quality of life, with the exception of "pain" domain.
conclusionsThe preference-based EQ-5D and SF-6D instruments showed valid psychometric properties to assess generic outcome in a Spanish population who had undergone surgery for lumbar disc herniation; however, utility scores derived from the measures were different. Thus, these two instruments cannot be used interchangeably to perform a cost-utility analysis, and they should both be included in sensitivity analyses.
