Visualizing the randomized sham-controlled trial in orthopedic research: proposed steps to conducting a total knee arthroplasty randomized controlled trial.
Review in Journal of comparative effectiveness research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Performed more than 600,000 times annually in the USA alone, total knee arthroplasty is the one of the most common and costly elective operations in the world. A primary total knee arthroplasty is generally an elective procedure, for which total index hospitalization costs are estimated around $30,000 USD. Roughly four in five patients declare they are satisfied postoperatively, justifying the procedure's frequency and high costs. It is sobering to realize, however, that the evidence base in favor of this procedure remains circumstantial. We as a profession lack randomized trials showing a subjective improvement over placebo intervention. We argue for the necessity of sham-controlled surgical trials in this setting and provide a surgical atlas showing how a sham operation may be performed.
