Hysteroscopic cervical features associated with difficult embryo transfer in unselected patients undergoing in vitro fertilization.
Article in Biomedical journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe most appropriate diagnostic tests for the assessment of the uterine cavity in patients undergoing standard infertility evaluation in daily practice remain unclear. Routine hysteroscopic uterine cavity evaluation before an in vitro fertilization-embyo transfer (IVF-ET) cycle is not a uniformly accepted procedure. However, cervical findings associated with difficult ET have rarely been reported in previous hysteroscopic studies. The main objective of this study was to examine the relationship between cervical finding under flexible outpatient hysteroscopy (OH) and difficult ET.
methodsA cohort clinical study was conducted with 650 patients undergoing their first in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) from January 2010 to December 2017. Of them, 605 women with available embryos underwent transfer cycles. Outpatient hysteroscopies were scheduled during the follicular phase of the menstrual cycle, 1-3 months before starting IVF/ICSI treatment.
resultsAmong the 650 women who underwent transvaginal sonography (TVS) and OH, abnormal sonographic findings were observed in 51 women (7.8%) in which submucous myoma, endometrial polyp, and endometrial hyperplasia were the most common. Abnormal hysteroscopic intracavitary findings were observed in 158 cases (24.3%) in which endometrial polyp, submucous myoma, and intrauterine adhesions were the most common. These results showed that TVS was specific (100%) but not sensitive (32.3%) compared with OH. Embryo transfer (ET) was difficult in 25% of women with cervical stenosis (CS) or tortuous cervical canal (TC) and was significantly more difficult in women in the TC group (30.7%) than in the CS group (19.6%).
conclusionOH can identify cervical charactistics associated with a high incidence of difficult ET.
