Incidence and risk factor evaluation for postoperative nausea and vomiting in cesarean section under general anesthesia compared to the gynecologic surgery: A retrospective study.

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
aimThis retrospective study sought to investigate the incidence of postoperative nausea and vomiting (PONV) and its associated risk factors in patients undergoing cesarean section under general anesthesia.
methodsPatients who underwent cesarean section under general anesthesia or who underwent open gynecologic surgery were assigned to the OB group (n = 291) or the GY group (n = 225), respectively. The primary outcome was the incidence of PONV. Multivariable logistic regression analysis was performed to identify independent risk factors for PONV in the OB group. Propensity score matching was additionally conducted to facilitate a comparison of PONV incidence between the OB and GY groups (n = 66 in each group).
resultsIn the OB group, 21 patients (7.2%) experienced PONV, which was significantly lower than the 68 patients (30.2%) in the GY group (p < 0.001). This difference remained statistically significant after propensity score matching (15.2% in the OB group vs. 31.8% in the GY group; p = 0.019). In multivariable logistic regression analysis of the OB group, abdominal surgical history (p = 0.032), longer surgical duration (p = 0.017), lower fluid intake (p = 0.011), and higher estimated blood loss (p = 0.009) were associated with PONV.
conclusionsPONV may occur less frequently in patients undergoing cesarean section under general anesthesia than in those undergoing gynecologic surgery. In obstetric patients, substantial intraoperative blood loss with inadequate fluid replacement, prolonged surgical duration, and a history of abdominal surgery may represent additional risk factor for PONV.
