Effect of a combined thermal protection strategy with plantar hot salt packs on preventing intraoperative hypothermia during knee arthroscopy: a randomized controlled trial.
Trial report in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study aimed to evaluate the efficacy of a combined thermal protection strategy incorporating plantar hot salt packs for preventing intraoperative hypothermia in patients undergoing knee arthroscopy. This randomized controlled trial enrolled 120 patients undergoing knee arthroscopy between January 2024 and December 2024. Patients were randomly assigned to either the experimental group (n = 60), which received routine care plus plantar hot salt packs, or the control group (n = 60), which received routine thermal care alone. The primary outcome was core body temperature, recorded at the following time points: admission (T0), 15 min after anesthesia induction (T1),3 0 min after surgery initiation (T2), at the end of surgery (T3), and upon arrival in the anesthesia recovery room (T4). Secondary outcomes included the incidence of intraoperative hypothermia, postoperative chills, patient comfort, and satisfaction. After adjusting for baseline temperature (T0) using analysis of covariance (ANCOVA), the experimental group maintained significantly higher core body temperatures at T1, T2, T3, and T4 than the control group (all adjusted P < 0.001). No significant between-group differences were observed in the incidence of intraoperative hypothermia or postoperative chills (both P > 0.05). Patient comfort was significantly higher in the experimental group (P < 0.05). Although patient satisfaction was numerically higher in the experimental group (98.3% vs. 88.3%), the difference was not statistically significant (P = 0.061). A combined thermal protection strategy using plantar hot salt packs effectively maintains perioperative core body temperature and significantly improves patient comfort during knee arthroscopy. While this strategy did not significantly reduce the incidence of hypothermia or chills, it represents a safe, non-invasive, and easily implemented adjunctive warming method that may help optimize intraoperative temperature management.Trial registration: Chinese Clinical Trial Registry, ChiCTR2600120304 (registered March 12, 2025).
