Evaluating change using patient-reported outcome measures in knee replacement: the complementary nature of the EQ-5D index and VAS scores.
Article in The European journal of health economics : HEPAC : health economics in prevention and care, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled it.
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
purposeUsing the UK National Health Service's Patient Reported Outcome Measures data, we examined the magnitude of changes and relationship among the EQ-5D index, EQ-5D Visual Analog Scale (EQ-VAS), and Oxford Knee Score (OKS) in patients undergoing knee replacement.
methodsPatients undergoing knee replacements in 2009-2011 completed the EQ-5D and OKS before and after surgery. Responsiveness was compared using the standardized response mean (SRM). Stratified analyses based on change scores in the OKS were utilized to investigate how changes in the outcome measures related to each other. Patients were grouped based on the preoperative OKS to examine the relationship of change in the EQ-5D index and EQ-VAS with respect to initial health status.
resultsFor the overall cohort (54,486 patients), mean change scores pre/post knee replacement were 0.30 for the EQ-5D index (SD 0.33; SRM = 0.90), 3.3 for the EQ-VAS (SD 21.0; SRM = 0.16), and 14.9 for the OKS (SD 9.9; SRM = 1.50). The OKS changed uniformly with the EQ-5D index, but less concordantly with the EQ-VAS in response to knee replacement surgery. Substantial functional improvement was needed before mean EQ-VAS change scores showed improvement. Patients with worse preoperative health status had greater improvement following surgery, but the improvement in the EQ-5D index did not necessarily translate into comparable improvement in self-perceived well-being measured by the EQ-VAS.
conclusionsOn average, patients self-rated their health systematically lower using the EQ-VAS compared to the EQ-5D index and OKS following knee replacement. The EQ-VAS captured information about how patients feel about their health pre-/post-surgical intervention that contrasted with more functional measures of health. Additional qualitative research is needed to better understand these differences.
