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
backgroundFinger joint arthrosis frequently results from trauma, degenerative or inflammatory causes. When conservative treatment and joint-preserving procedures fail, arthrodesis remains a reliable surgical option to relieve pain and restore hand function. Among the various techniques, the cup and cone method has proven particularly effective due to its large cartilage-free surface area and ease of intraoperative axis correction. The aim of this study is to evaluate this based on the patient cohort of a supramaximum care provider. MATERIAL AND
methodsA retrospective analysis of 201 finger joint arthrodeses in 168 patients was conducted between 2015 and 2025. Data collected included demographics, joint location, surgical indications and postoperative complications. A subgroup analysis of arthrodesis performed for degenerative osteoarthritis included comparison of preoperative and postoperative axis deviation and flexion angles per joint type.
resultsPatients had a mean age of 60 years and 71% were male. The right hand was affected in 54% of cases. Most arthrodeses involved proximal interphalangeal (PIP) joints (104), followed by distal interphalangeal (DIP, 65) and thumb IP joints (16). The leading indication was posttraumatic arthritis (48%), followed by degeneration (20%). Complication rates were low, with infection being the most common. In degenerative osteoarthritis cases, significant postoperative reductions in axis deviation were observed (up to 25°).
conclusionArthrodesis of the finger joints is an effective measure for improving function and relieving symptoms in treatment-refractory cases. The cup and cone technique has proven to be a procedure with a high success rate and a low complication rate. Individual planning of joint positioning and careful selection of the surgical technique are crucial for the functional outcome. Future prospective studies should further investigate long-term effects and patient satisfaction.
