Fertility outcomes in women undergoing Assisted Reproductive Treatments after COVID-19 vaccination: A prospective cohort study.
Article in International journal of fertility & sterility, 2024. 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
backgroundVaccination against Coronavirus-19 disease (COVID-19) was widely administered from 2021 onwards. There is little information on how this vaccine affected fertility after assisted-reproductive-technology (ART). The aim of this study therefore was to determine if COVID-19 vaccination or time-since-vaccination influenced ART outcomes. MATERIALS AND
methodsIn this prospective cohort study, 502 oocyte-retrieval-cycles and 582 subsequent embryo- transfer-cycles were grouped based on COVID-19 vaccine status of the female partner into those with no-exposure, 1-dose and ≥2-dose exposure. Within the exposed cohort, time-since-last-vaccination to embryotransfer- cycle (T
resultsMean-total-utilizable-embryos and mean-oocyte-utilization-rate per oocyte-retrieval-cycle in no-exposure, 1-dose and ≥2 dose were 2.7 ± 1.8 vs. 2.5 ± 1.9 vs. 2.7 ± 2.0, P=0.78, (ß=0.42, 95% confidence-interval (CI)=0.15 to 0.69) and 21.2 ± 13.2 vs. 25.1 ± 19.0 vs. 26.7 ± 18.8, P=0.08, (ß=3.94, 95% CI=1.26 to 6.23) respectively. Ongoing-pregnancy-rates and pregnancy-loss-rates per embryo-transfer-cycle were 27.3% vs. 24.4% vs. 32.5% (aOR=1.38, 95% CI=0.3-5.6, P=0.52), and 13.6% vs. 13.4% vs. 15.2%, (aOR=0.97, 95% CI=0.18-5.2, P=0.97) respectively. Cumulative-ongoing-pregnancy-rates per oocyte-retrieval-cycle were 36.5% vs. 34.5% vs. 35.5% (aOR=1.53, 95% CI=0.57 to 4.07, P=0.35). Median T
conclusionCovid-19 vaccination does not negatively influence embryological-outcomes or cumulative-ongoing-pregnancies after ART-treatments. Duration since vaccination may have a weak negative effect on embryo-transfer-outcomes performed within 60 days.
