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

purposeTo evaluate whether outcomes of in vitro fertilization (IVF) are affected during the coronavirus disease-19 (COVID-19) pandemic.

methodsThis was a single-center, retrospective study. Embryo development, pregnancy, and live birth outcomes were compared between COVID-19 and pre-COVID-19 groups. Blood samples from patients during the COVID-19 pandemic were tested for COVID-19.

resultsAfter 1:1 random matching, 403 cycles for each group were included in the study. The rates of fertilization, normal fertilization, and blastocyst formation were higher in the COVID-19 group than in the pre-COVID-19 group. No difference was observed in the rates of day 3 good-quality embryos and good-quality blastocysts between the groups. A multivariate analysis showed that the live birth rate in the COVID-19 group was higher than that in the pre-COVID-19 group (51.4% vs. 41.4%, P = 0.010). In fresh cleavage-stage embryo and blastocyst transfer cycles, there were no differences between the groups in terms of pregnancy, obstetric, and perinatal outcomes. In the freeze-all cycles, the live birth rate was higher during the COVID-19 pandemic (58.0% vs. 34.5%, P = 0.006) than during the pre-COVID-19 period following frozen cleavage stage embryo transfer. The rate of gestational diabetes during the COVID-19 pandemic was higher than that during the pre-COVID-19 period (20.3% vs. 2.4%, P = 0.008) following frozen blastocyst transfer. All the serological results of the patients during the COVID-19 pandemic were negative.

conclusionOur results indicate that embryo development, pregnancy, and live birth outcomes in uninfected patients were not compromised during the COVID-19 pandemic at our center.
