[Influence of institutional experience on results in hip and knee total arthroplasty : An analysis from the German arthroplasty registry (EPRD)].
Article in Der Orthopade, 2020. 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
backgroundThe German Arthroplasty Registry, EPRD, has the ability to examine early factors influencing the probability of failure of total hip arthroplasty (THA) and knee arthroplasty (TKA). The study analyses the influence of the overall experience of a hospital, as well as the change in supplier on the revision rate. MATERIALS AND
methodsA total of 164,903 cementless THA and 155,577 cemented TKA were in follow-up from 656 hospitals from 2012 to 2019. The number of arthroplasties performed per hospital per year was used as a surrogate parameter for institutional experience. This number was subdivided into 250, 251-500 and more than 500 for hip and knee per year and the overall revision rate was analysed. Additionally, the effects of the change of a major supplier of implant systems to a hospital were analysed. At least 70% of the documented implant components for each calendar quarter were used in that hospital to define the company as a major supplier.
resultsThe overall revision rate for THA was 3.9% for hospitals with up to 250 arthroplasties per year, 3.3% for hospitals with 251-500 arthroplasties per year and 2.9% for hospitals performing over 500 surgeries per year (p < 0.0001). The revision rate for TKA was also significantly different between the three groups with 3.4, 3.3 and 2.7% (p < 0.0001). Changing the supplier of implant systems also showed a significant increase of the revision rate (p < 0.0001 for THA, p = 0.02 for TKA).
conclusionThe institutional experience significantly influences short-term results in terms of the revision rate of hip and knee arthroplasty. Changing the implant system even in an experienced hospital has a major impact on the early revision rate and, therefore, needs careful transition.
