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.

2 · The registry

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

objectiveRacial variation in total knee replacement (TKR) utilization in the United States has been reported in administrative database studies. We investigated racial variation in TKR procedures in a diverse cohort with severe knee pain followed in an ongoing clinical trial.

methodsVITAL (VITamin D and OmegA-3 TriaL) is a nationwide, randomized controlled trial of 25,874 adults, 20% of whom are black. We identified a subgroup highly likely to have knee osteoarthritis based on severity of knee pain, physician-diagnosed knee osteoarthritis, and inability to walk 2 to 3 blocks without pain. Participants completed a modified Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at baseline and self-reported incident TKR annually in follow-up. Using Cox regression, we analyzed the association of black versus white race with TKR, adjusting for demographic and socioeconomic characteristics, comorbidities, and WOMAC pain and function.

resultsAmong 1070 participants who met the inclusion criteria, black participants reported worse baseline WOMAC pain (45 vs. 32, P < 0.001) and worse function (45 vs. 32, P < 0.001). During a median of 3.6 years (interquartile range, 3.2, 3.8 years) of follow-up, TKRs were reported by 180 participants. Black participants were less likely to undergo TKR (11% vs. 19%). After adjustment, the hazard ratio for TKR for black versus white participants was 0.51 (95% confidence interval, 0.32-0.81). Lower use of TKR among black participants was observed across all levels of income and education.

conclusionsDespite worse baseline knee pain and function, black participants had much lower adjusted risk of having TKR than white participants, demonstrating persistent racial disparity in TKR utilization.
