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
Objective: The effects of neuromuscular blockade reversal agents on maternal endocrine physiology during cesarean section remain poorly understood. Sugammadex, a selective γ-cyclodextrin that encapsulates aminosteroid neuromuscular blockers, may transiently interact with endogenous steroid hormones due to its structural affinity. This study compared the impact of sugammadex and neostigmine on maternal steroid and lactation-related hormones during cesarean delivery under general anesthesia. Materials and Methods: In this randomized and controlled trial, 44 parturients (≥37 weeks) undergoing cesarean section under general anesthesia received either 2 mg/kg sugammadex or 0.03 mg/kg neostigmine for neuromuscular blockade reversal. Serum concentrations of progesterone, estradiol, aldosterone, cortisol, prolactin, and oxytocin were measured preoperatively, at the end of surgery, and at 15 minutes and 4 hours postoperatively. Results: Both groups showed significant decreases in progesterone and estradiol levels after surgery compared to preoperative values; however, the sugammadex group exhibited a greater decrease (p<0.05). Aldosterone levels reached their highest point at the end of surgery, but by 4 hours later they were lower than before surgery, especially in the sugammadex group (p<0.001). Cortisol showed a temporary postoperative elevation, whereas prolactin and oxytocin levels rose in both groups, with no significant intergroup variations. Conclusion: Sugammadex induces a short-term suppression of maternal steroid hormones, particularly progesterone and estradiol, but does not affect lactation-related hormones. Measured hormone levels returned to near preoperative values within four hours, and no clinically significant adverse outcomes were associated with these temporary hormonal changes, supporting the safety of sugammadex use in obstetric anesthesia.
