Vital signs following autotransfusion in liposuction and concurrent aesthetic procedures.
Article in Revista do Colegio Brasileiro de Cirurgioes, 2025. 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
introductionLiposuction might lead to complications such as bleeding and anemia, and the volume of blood lost cannot be predicted. Autotransfusion has hemodynamic benefits and may be associated with better patient recovery.
objectiveTo evaluate whether Autolog IQTM impacts the vital signs of patients undergoing liposuction.
methodsA retrospective case-control study with patients undergoing liposuction from July to November 2023. Observers were blinded to data collection and analysis, and 98 patients were included and classified into an intervention group (autotransfusion during the procedure) or control group.
results49 patients used Autolog, and 49 patients made up the control group, selected conveniently. 94 patients (96%) were women, with a mean age of 39±9.17 years and a mean weight of 26.5±3.55kg. Heart rate (HR) response in the postoperative period (MD -12, 95% CI: -19.42 to -4.58, p=0.002) and during anesthesia recovery (MD -8, 95% CI: -13.56 to -2.44, p=0.005) compared to the perioperative period favored the Autolog group. Mean arterial pressure during anesthesia recovery compared to the perioperative period (MD -25, 95% CI: -30.5 to -19.95, p<0.001); the MEWS score at hospital discharge (MD 1, 95% CI: 0.56 to 1.44, p<0.001); and HR at hospital discharge compared to postoperative (MD 10.5, 95% CI: 2.5 to 18.5, p=0.01) and anesthesia recovery (MD 8, 95% CI: 1.45 to 14.55, p=0.02) favored the control group.
conclusionsAutotransfusion showed potential benefits in immediate postoperative heart rate response and anesthesia recovery. Broader studies are needed in this population.
