Management and outcome of prenatal absent pulmonary valve syndrome.
Article in Archives of gynecology and obstetrics, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThe purpose of this study was to explore the outcome in fetuses with prenatal diagnosis of absent pulmonary valve syndrome (APVS) on ultrasound imaging.
methodsA manual web scraping technique was utilized, where MEDLINE and EMBASE were searched along the combination with other relevant medical subject headings such as "absent pulmonary valve syndrome", "prenatal APVS" and "APVS/outcome". The observed outcomes encompassed the rate of chromosomal abnormalities, associations and malformations linked to APVS and fetuses with APVS. A quality assessment of the included studies was also performed. We used meta-analyses of proportions to combine data and fixed or random-effects models according to the heterogeneity of the results.
resultsSeven studies including 199 fetuses with APVS were included in the analysis. The median gestational age at referral to the tertiary center was 24.8 weeks. An association to tetralogy of Fallot (TOF) could be seen in 84.4% of all cases. In total 140 out of 199 cases underwent invasive testing, with a total number of 55 abnormal karyotypes [39.3% (95% CI 31.1-47.9%)]. 35.2% of the patients opted for termination of pregnancy (95% CI 28.5-42.3%).
conclusionThe analysis underlines the distribution of fetuses with APVS, with 84.4% of cases presenting with TOF/APVS and only 12.6% having APVS/intact ventricular septum (IVS). Larger and more prospective study analyses is now needed, especially focusing on long-term follow-up periods of fetuses and children with APVS. Particularly as the postnatal course shows great variety depending on prenatal diagnosis.
