1 · What the graph read from it

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.

2 · The registry

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

objectivesThis study aimed to investigate the beneficial effects of single-joint hybrid assistive limb (HAL-SJ)-assisted rehabilitation after total knee arthroplasty (TKA), with a focus on the early postoperative period.

methodsThis single-anonymized randomized controlled trial assigned 72 participants who underwent primary TKA for knee osteoarthritis to the HAL-SJ (n=35) and control groups (n=37). The passive knee range of motion (ROM; i.e., the primary outcome) was evaluated preoperatively and at 1 week, 2 weeks, and 3 months postoperatively. Extension lag and knee pain intensity scores were evaluated preoperatively and at 1 and 2 weeks postoperatively. Quadriceps and hamstring isometric knee strength and walking speed were evaluated preoperatively and at 2 weeks postoperatively. The Knee Injury and Osteoarthritis Outcome Score (KOOS) was evaluated preoperatively and at 3 months postoperatively.

resultsCompared with the control group, the HAL-SJ group showed significantly improved knee extension ROM (p=0.001) and greater KOOS Activities of Daily Living subscale score (p=0.005) at 3 months postoperatively, with a significantly early improvement in extension lag (p=0.001) and hamstring strength (p=0.012) at 2 weeks postoperatively.

conclusionsHAL-SJ effectively supports postoperative rehabilitation, showing clinical advantages for improving daily activities by 3 months after TKA. CLINICAL
