Hip score and disease activity correlation in patients with rheumatoid arthritis after total hip arthroplasty.
Observational study in International orthopaedics, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeThe disease activity score including 28 joints (DAS28), the simplified disease activity index and the clinical disease activity index (CDAI) were developed in order to provide a quantifiable measure of rheumatoid arthritis (RA) activity. Although inflamed hip joints greatly impact activities of daily living (ADL) and walking ability, the hip joint was not included in the DAS28, SDAI or CDAI assessments. Although excellent clinical results have been reported for total hip arthroplasty (THA) in RA patients, correlations between disease activity and hip function in RA patients after THA remain unknown.
methodsWe analysed the effect of RA disease activity on a hip function score in an observational cohort of RA patients after THA. Twenty-five registered RA patients who had undergone THA (33 joints) were included. Hip function was recorded and RA disease activity was measured on the same day. The mean age of the patients was 65.17 years. They were followed up for a mean of 5.24 years after surgery. The mean duration of disease following RA diagnosis for this patient group was 19.47 years. The Japanese Orthopaedic Association (JOA) hip score was used as a clinical outcome measure for hip dysfunction. RA disease activity and health-related quality of life were measured using the DAS28, SDAI, CDAI and the modified health assessment questionnaire (MHAQ).
resultsThe mean JOA score for hip function was 80.48 at the final follow-up. The mean DAS28-ESR, DAS28-CRP, SDAI, CDAI and MHAQ measuring RA disease activity levels were 3.38, 2.65, 9.59, 8.63 and 0.44, respectively, at the final follow-up. There was a significant negative correlation between the JOA hip score and all disease activity assessments observed after THA (DAS-ESR [P = 0.0067], DAS-CRP [P = 0.0008]), SDAI [P = 0.0034], CDAI [P = 0.0003]) and MHAQ [P = 0.0002]).
conclusionWe found significant negative correlations between JOA hip scores and all disease activity assessments in RA patients treated with THA.
