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
introductionTotal wrist arthroplasty (TWA) has evolved as a motion-preserving alternative to arthrodesis, offering improved pain relief, functional outcomes, and patient satisfaction. The fourth-generation Motec wrist prosthesis, a cementless, ball-and-socket, metal-on-metal implant, has demonstrated encouraging mid- to long-term results. However, TWA remains a technically demanding, low-volume procedure with a steep learning curve. Dual-consultant operating has been proposed as a method to optimize learning outcomes and reduce complications, but evidence remains limited.
methodsA retrospective service evaluation was conducted on all Motec TWA procedures performed between September 2021 and November 2024 by six fellowship-trained hand surgeons at Kent and Canterbury Hospital. Nineteen patients met the inclusion criteria and were divided into dual-consultant (n = 14) and single-consultant (n = 5) groups. Complications were classified according to the Clavien-Dindo system, and surgeon expertise was categorized per the Tang and Giddins classification. Statistical analysis was performed using Fisher's exact test.
resultsNineteen patients were evaluated, including 14 operated by dual consultants and 5 by a single consultant. In the dual-consultant group, 7 patients (50%) had no complications, 4 (28.6%) had Grade I, and 3 (21.4%) had Grade II complications. In the single-consultant group, 2 patients (40%) had no complications, 2 (40%) had Grade I, and 1 (20%) had a Grade IV complication. Conclusion: Dual-consultant operating did not confer a statistically significant reduction in complications; however, an absence of severe complications in dual cases suggests potential benefits in safety and mentorship. Given the small sample size and high baseline expertise of surgeons, larger, prospective, multicenter studies are warranted to define the role of dual-consultant surgery in TWA.
