Factors influencing intraoperative blood loss in bimaxillary orthognathic surgery.

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
backgroundThe study aimed to investigate the risk factors that could affect intraoperative blood loss in patients who underwent orthognathic surgery. MATERIAL AND
methodsThe study included a retrospective analysis of 400 patients who underwent bimaxillary orthognathic surgery. Data on demographic, surgical, and hematological parameters affecting intraoperative blood loss were statistically analyzed.
resultsThe mean intraoperative blood loss of male patients was statistically higher than that of female patients (p ≤ 0.001). The mean blood loss was higher in patients aged 25 years and older than in patients aged 17-24 (p=0.004). Patient weight and duration of surgery were positively correlated with the amount of intraoperative bleeding (r = 0.280 and r = 0.371). Platelet (PLT) count negatively correlated with blood loss (r=-0.213). The MPV/PLT ratio and hemoglobin (HGB) levels were positively correlated with bleeding (r=0.208 and r=0.110).
conclusionsIn orthognathic surgeries, factors such as age, gender, body mass, and duration of surgery were found to be associated with intraoperative blood loss. Males, patients over 24, overweight patients, and prolonged surgical procedures are all significant risk factors for bleeding. In addition, high HGB levels, low platelet count, and low MPV/PLT ratios are also associated with an increased risk of blood loss.
