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
Intra-articular platelet-rich plasma (PRP) injections represent a promising biological treatment for early-stage knee osteoarthritis (KOA). As cord blood-derived PRP (CB-PRP) contains higher levels of bioactive mediators, this prospective study aimed to compare the efficacy and safety of CB-PRP versus homologous donor PRP (HD-PRP) in patients with early KOA and to evaluate whether CB-PRP results in greater clinical improvement. Fifty-one patients aged 46-70 years with Kellgren-Lawrence grade 1-2 were randomized to receive either CB-PRP or HD-PRP. Each underwent three intra-articular injections at four-week intervals. Outcomes included pain-related overall health perception assessed by the EuroQol Visual Analogue Scale (EQ-VAS), function measured with the Knee Injury and Osteoarthritis Outcome Score (KOOS), and quadriceps muscle strength evaluated by dynamometry. Assessments were performed at baseline and at 1, 2, 3, 6, and 12 months. Both groups showed improvements in pain and function over 12 months, with no statistically significant between-group differences (
