Article in Arthroplasty today, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07439315 (The Effect of a Novel Joint Distraction Knee Orthosis for Treating Medial Knee Osteoarthritis), which is not on this map. Cited by 23 papers, 1 of them a synthesis that pooled it.

1 · What the graph read from 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.

Abstract

backgroundLittle is known about the persistence of health disparities in joint arthroplasty. The objective of this study was to update our knowledge on the state of racial and ethnic disparities in total hip arthroplasty (THA).

methodsPatients undergoing primary, elective THA using the 2011-2017 American College of Surgeons National Surgical Quality Improvement Program were retrospectively reviewed. Five minority groups (non-Hispanic black or African American, Hispanic or Latino, Asian, American Indian or Alaska Native, and Native Hawaiian or Pacific Islander) were compared with non-Hispanic whites. The primary outcomes were in the differences in demographic characteristics, comorbidities, perioperative characteristics, THA utilization, length of stay (LOS), and 30-day adverse events (mortality, readmission, reoperation, and complications).

resultsA total of 155,870 patients were identified with racial and ethnic data available on 134,961 (86.6%) of them. Non-Hispanic white patients comprised 74.5% of all THA procedures. Except for Asians, all minority groups were more likely to be younger, have a higher body mass index, and smoke tobacco (

conclusionsHealth disparities persist among minority groups with respect to comorbidities, THA utilization, LOS, and complications. Blacks and Hispanics or Latinos appear to be the most impacted by these disparities.
