A Randomized Trial Comparing Potato Poultice Compress Versus Traditional Medicated Compress for Forearm Swelling After Trans-Radial Percutaneous Coronary Intervention.

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
Forearm swelling and associated discomfort are common sequelae of percutaneous coronary intervention (PCI); however, evidence guiding effective and practical nursing management remains limited.
aimThis study compared the efficacy of a potato-derived compress with that of a conventional medicated compress (containing magnesium sulfate, lidocaine, and dexamethasone) in reducing forearm swelling and improving patient-centered outcomes following PCI.
methodsSixty-two patients presenting with post-intervention forearm swelling were randomly assigned to receive either a raw potato‑puree compress (n = 31) or a conventional medicated compress (n = 31). Measurements of forearm circumference, swelling length, pain intensity, peripheral oxygen saturation (SpO
resultsWhen comparing pre‑to‑post intervention change scores, the potato compress group demonstrated significantly greater reductions in swelling circumference and length compared to the medicated compress group. The potato group also showed significantly lower pain scores and significantly higher comfort scores. No significant difference in peripheral oxygen saturation was observed between groups.
conclusionFor nursing management of post‑intervention forearm swelling, a raw potato‑puree compress appears to be a safe, low‑cost, and promising alternative to the standard pharmaceutical compress, showing superior effects on pain and comfort as well as greater reduction in swelling from baseline to post‑intervention.
