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
backgroundDorsal fracture-dislocations of the proximal interphalangeal (PIP) joint often lead to stiffness, pain, and post-traumatic osteoarthritis (PTOA). This study evaluated long-term clinical outcomes and radiographic PTOA following surgical treatment of unstable PIP fracture-dislocations.
methodsWe conducted a retrospective cohort study of 25 patients (27 fingers) treated with extension block pinning for unstable dorsal PIP fracture-dislocations between 2000 and 2009. Follow-ups in 2010 and 2021 assessed active range of motion (AROM) in PIP and distal interphalangeal (DIP) joints, grip strength, and pain. Postoperative radiographs were analyzed for articular surface involvement and step-off. Post-traumatic osteoarthritis was graded using Kellgren-Lawrence, Kallman, and Osteoarthritis Research Society International scales by 3 blinded hand surgeons, with intraobserver and interobserver reliability assessed.
resultsOver a follow-up of up to 16 years, PIP AROM remained stable. Patients aged ≥45 had reduced PIP AROM and more frequent pain. Greater pain was also seen in those with >0.5 mm articular step-off or advanced radiographic osteoarthritis (OA). Osteoarthritis progression was associated with reduced PIP AROM and residual step-off. The Kallman scale showed the most significant OA progression, especially with ≥50% joint surface involvement. Osteoarthritis grading showed substantial intraobserver and interobserver reliability.
conclusionLong-term function after extension block pinning of dorsal PIP joint fracture-dislocations remained, though age over 45 years and residual step-off predicted reduced AROM, pain, and OA progression.
