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
Objectives: This study aimed to investigate the prevalence and risk factors of mechanical pain in patients with advanced knee osteoarthritis (KOA), providing insights for targeted treatment approaches. Methods: We conducted a cross-sectional study involving 920 patients with KOA. The sample size was determined using the formula Results: Among participants, 43.48% experienced simple mechanical pain, 33.48% had mixed mechanical pain, and 23.04% reported probable NP. Significant differences were observed in the total WOMAC scores, range of motion (bend), and NRS across the three groups. Gender distribution varied significantly, with a higher proportion of female patients in each pain category. Notably, NRS on the affected side was moderately correlated with the total WOMAC pain score ( Conclusions: Mechanical pain is highly prevalent in patients with advanced KOA. Identifying the specific type of mechanical pain and associated risk factors, such as female gender and higher NRS score, can facilitate personalized pain management.
