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

introductionTo report the progress of the human living uterus transplant research project in Singapore. MATERIAL AND

methodsThe uterus transplant research project began in 2012 with a collaboration between the Swedish and Singapore teams. Ethics approval was obtained from the SingHealth Centralised Institutional Review Board, the SingHealth Transplant and the Singapore General Hospital Biomedical Ethics Committee to perform 5 uterus transplant procedures in a collaborative multi-site research study at the Singapore General Hospital. Regulatory approval was obtained from the Ministry of Health, Singapore. A suitable recipient-donor pair was identified. The living donor was the perimenopausal mother-in-law of the recipient who had Mayer-Rokitansky-Kuster-Hauser syndrome. They underwent the requisite matching process as well as robust medical, psychiatric and psychosocial assessments. The recipient then underwent in vitro fertilization (IVF) treatment resulting in 6 frozen blastocysts. Preparations were made for the transplant surgery on 25 November 2023 in Singapore General Hospital, aided by the 3 Uterus transplant experts from the Swedish Team, for whom temporary registration was granted by the Singapore Medical Council.

resultsThis first uterus transplant procedure involved an operative time of 10 h and 30 min for the donor. The synchronized recipient surgery lasted 6 h and 20 min. Surgery was by midline laparotomy in both the living donor and recipient. The total warm ischemic time of the graft was 45 min, and the cold ischemic time was 1 h 45 min (total ischemic time 2 h 30 min). The patient's first menstruation occurred 38 days after the uterus transplant procedure. Cytomegalovirus infection was detected 6 weeks postoperatively for which she was aggressively treated. Serial cervical biopsies showed no rejection and Doppler ultrasound of the transplanted uterus showed good uterine blood flow.

conclusionsTo date the Living Donor Uterus Transplant Research Project in Singapore has progressed with a uterus transplant surgery involving a living donor performed by a multidisciplinary team. The recipient had a menstrual period 38 days postoperatively. Further study of the outcomes from this procedure will inform the safety and efficacy of uterus transplant in the Singapore context.
