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 Swelling of the knee after total knee arthroplasty (TKA) impairs postoperative motor function. This study aimed to investigate whether knee swelling after TKA affects motor function and whether 2 weeks of compression intervention can improve postoperative motor recovery. Methods We screened 120 patients undergoing unilateral TKA. After exclusions and loss to follow-up, 88 patients were analyzed (compression group n=46; control group n=42). Outcomes (circumference, knee range of motion (ROM), pain, knee extensor strength, and walking speed) were assessed preoperatively and at 2 weeks after TKA. Statistical analyses were performed to compare the two groups. Results Swelling was significantly reduced in the compression group compared to the control group (36.4±2.6 cm in the compression group and 38.0±3.1 cm in the control group; p=0.014). Additionally, the ROM of knee extension (-1.1±2.1°in the compression group and -3.7±5.9°in the control group; p=0.015), pain at rest (6.1±15.1mm in the compression group and 15.9±19.1mm in the control group; p=0.001), muscle strength of knee extension (0.38±0.1Nm/kg in the compression group and 0.34±0.1Nm/kg in the control group; p=0.000), and gait speed (0.80±0.2m/s in the compression group and 0.75±0.2m/s in the control group; p=0.000) were significantly improved in the compression group. There was no significant difference in the ROM of knee flexion (113.6±13.0°in the compression group and 114.6±13.6° in the control group; p=0.708). Discussion To our knowledge, this is one of the few studies that have examined the effects of 2 weeks of knee compression on swelling and motor function after TKA. The compression group showed significantly higher improvement in motor function compared to the control group. Therefore, continuous compression for 2 weeks may be an effective method to reduce postoperative knee swelling and improve motor function after TKA. Conclusion It is suggested that compression of the knee for 2 weeks after TKA is useful in reducing swelling and improving motor function.
