Outcomes of assisted reproductive technology procedures performed on weekdays versus weekends: a retrospective cohort study.
Article in Journal of assisted reproduction and genetics, 2023. 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
purposeTo evaluate if assisted reproductive technology (ART) outcomes are different based on whether procedures - oocyte retrieval, insemination, embryo biopsy, or embryo transfer - are performed on a weekday versus weekend/holiday.
methodsRetrospective cohort study of all patients ≥ 18 years old who underwent oocyte retrieval for in vitro fertilization or oocyte banking (n = 3,197 cycles), fresh or natural-cycle frozen embryo transfers (n = 1,739 transfers), or had embryos biopsied for pre-implantation genetic testing (n = 4,568 embryos) in a large academic practice from 2015-2020. The primary outcomes were as follows: oocyte maturity for oocyte retrievals; fertilization rate for insemination; rate of no result on pre-implantation genetic testing for embryo biopsy; and live birth rate for embryo transfers.
resultsThe average number of procedures performed per embryologist per day was higher on weekends/holidays than weekdays. For oocyte retrievals performed on weekdays vs. weekends/holidays, there was no difference in oocyte maturity rate (88% vs 88%). There was no difference in the fertilization rate (82% vs 80%) in cycles that had intracytoplasmic sperm injection performed on weekdays vs. weekends/holidays. No difference was found in the no result rate for embryos biopsied on weekdays vs. weekends/holidays (2.5% vs 1.8%). Finally, there was no difference by weekday vs. weekend/holiday in the live birth rate per transfer among all transfers (39.6% vs 36.1%), or when stratified by fresh (35.1% vs 34.9%) or frozen embryo transfer (49.7% vs. 39.6%).
conclusionWe found no differences in ART outcomes among women who had their oocyte retrievals, inseminations, embryo biopsies, or embryo transfers performed on weekdays versus weekends/holidays.
