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

introductionHow can non-cultured platelet-rich plasma (PRP) therapy be the ultimate intervention in the treatment of total knee arthroplasty (TKA) -adaptive levels of knee osteoarthritis, as opposed to stem cell therapy that requires culture?

methodsAn intra-articular injection of leukocyte-rich PRP (LR-PRP) was administered to 260 patients every 4 weeks for over four times (mean 5.8 times); they were followed up for a maximum of 24 months. The clinical evaluation used the Knee Injury and Osteoarthritis Outcome Score, visual analogue scale, and magnetic resonance imaging osteoarthritis knee score-body mass lesions to determine the therapeutic effect using the Outcome Measures in Rheumatology-Osteoarthritis Research Society International responder criteria for osteoarthritis.

resultsAmong those administered with LR-PRP, the responder rate was 72.0%, 78.1%, 78.1%, and 77.1% at 3, 6, 12, and 24 months, respectively.

conclusionsOur manually prepared LR-PRP was effective following multiple consecutive injections, despite severe degeneration.
