Trapeziometacarpal Joint Arthroplasty: Medium-Term Clinical Outcomes and Survival.
Article in Cureus, 2024. 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
Trapeziometacarpal joint (TMC) arthroplasty (TMA) is a treatment option for failed symptomatic treatment of basal thumb arthritis. This study aimed to evaluate clinical and radiological outcomes and complications of Maïa™ prosthesis (Groupe Lépine, Genay, France) since its introduction in our institution with a minimum of three years follow-up. We performed a retrospective study of patients with TMA treated with Maïa prosthesis. Between 2015 and 2017, 22 patients (21 female and one male patient) were submitted to TMA with Maïa prosthesis, with a mean age of 60.1±6.6 (95%CI 57.1, 63.0) years old. According to the Eaton-Littler classification, four patients had rhizarthrosis grade II, and 18 had grade III. The average follow-up was 56.4±6.0 months (95%CI 53.8, 59.1). Mean TMC radial abduction was 53.0±15.9º (95%CI 43.1, 62.3), corresponding to 89% (95%CI 78, 100) of the contralateral side. The mean Kapandji score was 9.5±0.7 (95%CI 9.1, 9.8), corresponding to 98% (95%CI 94,100) of the opposite side. The mean key pinch was 4.7±1.4 kg (95%CI 3.9,5.4), and the mean grip strength was 8 kg (95%CI 4, 12) against 10 kg (95%CI 6, 14), which corresponded to 79% (95%CI 70, 88), and 81% (95%CI 66, 96) of the non-operated side force, respectively. The mean satisfaction score with the procedure was 8.8±2.3 (95%CI 7.6, 10.0) out of 10. The mean qDASH (Quick Disabilities of the Arm, Shoulder, and Hand) score was 25.8±30.0 (95%CI 10.0, 40.7). The total revision rate was 13.6% (two cases of dislocation and one for loosening of the trapezium cup). There were no infections. The survival rate of the implant was 86.4% (95%CI 78.3, 93.3) after a five-year follow-up. There is still limited information regarding the long-term results of TMA using the Maïa prosthesis. TMA is a technically demanding procedure with a significant learning curve. With this study, we report satisfactory medium-term results in terms of motion, strength, and patient satisfaction.
