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
Objective: To investigate the clinical outcomes of total knee arthroplasty (TKA) by using the condylar constrained knee prosthesis in the treatment of destructive hemophilic arthritis. Methods: Between September 2007 and July 2015, 8 cases (8 knees) of destructive hemophilic arthritis accepted TKA by using condylar constrained knee prosthesis. All patients were male, aged 22 to 56 years, with an average age of 35 years. The disease course of hemophilia A was 3-30 years (mean, 17.3 years). Preoperative range of motion (ROM) was (68.1±32.6)°; the flexion deformity was (14.38±16.13)°. Six patients had valgus of 7-35° (mean, 17.3°), of whom, one had fixed dislocation of patella; and one had varus of 15°. Hospital for Special Surgery (HSS) knee score was 52.5±12.9. Pre-operative X-ray film examination demonstrated narrowing of the knee gap and cystic degeneration of articular cartilage and subchondral bone. Results: All patients achieved primary wound healing, and were followed up 1-9 years (mean, 5 years). Tense blister with common peroneal nerve damage and extension penetrating into distal tibial cortex occurred in 1 case respectively, which were cured corresponding treatment. At last follow-up, the knee ROM and the flexion deformity were significantly improved to (98.1±8.9)° and (0.63±1.77)° ( Conclusion: Good curative effect can be get by using condylar constrained knee prosthesis in TKA for the treatment of destructive hemophilic arthritis.
