Middle Finger Metacarpophalangeal Joint Locked in Flexion Caused by Entrapped Ulnar Collateral Ligament.

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
Type 1 finger metacarpophalangeal (MCP) joint locking is characterized by maintained flexion of the MCP, with a lack of active and passive extension. Metacarpophalangeal joint locking is rare but has several identified causes, most commonly involving a radial-sided osteophyte. We report a case of right middle finger ulnar collateral ligament (UCL) entrapment characterized as type 1 MCP joint locking. The physical examination demonstrated that the right middle finger was locked in flexion at 60° at the MCP joint. Magnetic resonance imaging (MRI) demonstrated a possible tear of the distal attachment of the UCL at the MCP joint. Closed manipulation was unsuccessful in the office, and the patient underwent MCP ulnar osteophyte excision with full postoperative recovery. Although diagnosing the cause of UCL locking may be complicated by the lack of evidence in imaging studies, patients can return to full function by restoring the integrity of the joint with surgical treatment.
