1 · What the graph read from it

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.

2 · The registry

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

backgroundPlacenta previa (PP) involves abnormal placental implantation in the lower uterine segment, partially or completely covering the internal cervical os, and is linked to severe maternal hemorrhage and fetal complications. The optimal anesthetic method between general anesthesia (GA) and combined spinal-epidural anesthesia (CSEA) for cesarean delivery (CD) with PP remains controversial.

methodsWe retrospectively analyzed 550 PP-complicated CD cases from the Longitudinal Placenta Previa Study (LoPPS) conducted in Southwest China between January 2018 and December 2024. Patients received either GA (n = 170) or CSEA (n = 380). Sociodemographic, obstetric, perioperative, and neonatal data were compared. Multivariate linear and logistic regression was employed to assess the association between anesthetic methods and other perioperative factors, and intraoperative blood loss, or neonatal asphyxia while adjusting for potential confounders.

resultsPatients undergoing GA had a higher age (32.4 vs 31.5 years, p = 0.020), higher body mass index (BMI) (26.5 vs 23.5 kg/m

conclusionCSEA is a safe option for selected cases of PP-related CD, particularly in the absence of PAS or in cases with milder forms of PP. Though the GA group exhibited greater intraoperative blood loss, due to the significant differences in the indications for anesthesia methods and the observational nature of current study, this should not be simply interpreted as a causative effect of GA on higher intraoperative blood loss. Thorough antenatal ultrasound assessment of placental status is critical. For complex cases, such as those involving severe PAS subtypes or complete PP, coordinated multidisciplinary perioperative management is essential.
