Are joint replacement registries associated with burden of revision changes? A real-world panel data regression analysis.
Article in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesThe association of joint replacement registries with outcomes such as revision burden is uncertain. This study aimed to evaluate whether joint replacement registries are associated with the burden of revision changes while controlling for confounders that could affect the association.
designA longitudinal study involving a combination of cross-sectional and time series data from 1980 to 2018. The study was a panel regression analysis using the difference-in-difference method.
settingData from countries with joint replacement registries and countries without joint replacement registries were used. Registry data were obtained from joint replacement registries' annual reports, while non-registry data were obtained from each included country's pooled hospitals' annual revision burden reported in the literature. OUTCOME MEASURES: Changes in revision burden from 1980 to 2018 was the outcome measure. The revision burden in the registry periods of registry countries was compared with the non-registry periods of registry and non-registry countries.
resultsData were obtained from 12 registry periods and 8 non-registry periods. The average difference in revision burden in the registry periods of registry countries relative to the non-registry periods of registry and non-registry countries was statistically significant for hip, -3.80 (95% CI (-2.50 to -5.10); p<0.001) percentage points and knee, -1.63 (95% CI (-1.00 to -2.30); p<0.001) percentage points. This translates to a 19.30%, and 21.85% reduction in revision burden for hip and knee registries, for the whole sampling period.
conclusionJoint replacement registries are associated with a significant reduction in the burden of revision. Although revision burden reduces over time even without the registries, the establishment of joint replacement registries is associated with an increased reduction. The establishment of joint replacement registries in non-registry countries would be a worthwhile decision as it will further improve the outcomes of arthroplasty surgeries.
