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

objectiveTo analyze the early- to mid-term clinical efficacy of personalized 3D-printed structural metal spacer technology in reconstructing massive bone defects during complex total knee arthroplasty (TKA) and revision surgery.

methodsA single-center retrospective study was conducted on nine patients with severe bone defects who underwent TKA between 2018 and 2024. The general condition, surgical details, and clinical improvement of these patients were recorded and analyzed by clinical doctors.

resultsThe average surgical duration was 183.9 minutes (range, 125-240 minutes), with intraoperative blood loss of 133.3 mL (range, 100-200 mL). The average hospital stay was 18.2 days (range, 10-42 days), and the follow-up duration was 13.2 months (range, 2-57 months). The preoperative average American Knee Society Score of 51.2 points (range, 15-74 points) improved significantly to 95.0 points (range, 81-106 points) at the last follow-up. No cases of vascular or nerve injury, infection, fracture, or prosthetic loosening were observed.

conclusionThe precise manufacturing of customized spacers that seamlessly integrate with the patient's skeletal structure ensures stability, adaptability, and improved surgical outcomes.
