Does Progesterone Affect Perioperative Blood Loss during Posterior Spinal Fusion Surgeries in Female Patients with Adolescent Idiopathic Scoliosis? A Retrospective Study.
Article in Orthopaedic surgery, 2023. 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
objectiveMenstruation is considered a contraindication for elective surgery for higher operative blood loss. Progesterone is often used to postpone menstruation to avoid surgery during menstruation. This study aimed to explore whether using progesterone to postpone menstruation affects perioperative blood loss and complications in female patients with adolescent idiopathic scoliosis (AIS) who underwent posterior spinal fusion (PSF) surgery.
methodsA retrospective study was performed for female patients diagnosed with AIS who underwent PSF surgery between March 2013 and January 2021. Patients scheduled to undergo PSF surgery from 2 days before menstruation to 3 days after menstruation were treated with progesterone preoperatively. The patients were divided into two groups according to progesterone use (progesterone injection group; control group). Demographic and surgical data including intraoperative blood loss (IBL), normalized blood loss (NBL), total blood loss (TBL), transfusion rate, perioperative complications, postoperative drainage time, postoperative hospital stay, and preoperative coagulation function data were collected.
resultsA total of 206 patients were included in the study. Among them, the progesterone injection group included 41 patients, with an average age of 14.8 years. While the control group included 165 patients, with an average age of 14.9 years. The two groups were matched for age, height, weight, operation time, Risser sign, correction rate, mean curve Cobb angle, bending Cobb angle, number of internal fixations, and number of fused levels (all P > 0.05). Regarding coagulation function, no significant differences were found in thrombin time, activated partial thromboplastin time, fibrinogen, prothrombin time, and platelet count between the two groups (all P > 0.05). IBL, NBL, and TBL were higher in progesterone injection group; however, the difference was nonsignificant (all P > 0.05). Transfusion rate, perioperative complications, postoperative drainage time, and postoperative hospital stay were not statistically different between groups (all P > 0.05).
conclusionIntramuscular injection of progesterone to avoid menstruation during PSF surgery did not affect perioperative blood loss and complications in AIS patients. It may be a safe method for AIS patients to avoid menstrual problems affecting the operation time and receive PSF surgery as scheduled.
