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.

Abstract

objectiveTo evaluate the perinatal and maternal outcomes of pregnancies in women infected with SARS-CoV-2, comparing spontaneous and in vitro fertilization (IVF) pregnancies (with either own or donor oocytes).

designMulticenter, prospective, observational study.

setting78 centers participating in the Spanish COVID19 Registry. PATIENT(S): 1,347 pregnant women with SARS-CoV-2 positive results registered consecutively between February 26 and November 5, 2020. INTERVENTION(S): The patients' information was collected from their medical records, and multivariable regression analyses were performed, controlling for maternal age and the clinical presentation of the infection. MAIN OUTCOME MEASURE(S): Obstetrics and neonatal outcomes, pregnancy comorbidities, intensive care unit admission, mechanical ventilation need, and medical conditions. RESULT(S): The IVF group included 74 (5.5%) women whereas the spontaneous pregnancy group included 1,275 (94.5%) women. The operative delivery rate was high in all patients, especially in the IVF group, where cesarean section became the most frequent method of delivery (55.4%, compared with 26.1% of the spontaneous pregnancy group). The reason for cesarean section was induction failure in 56.1% of the IVF patients. IVF women had more gestational hypertensive disorders (16.2% vs. 4.5% among spontaneous pregnancy women, adjusted odds ratio [aOR] 5.31, 95% confidence interval [CI] 2.45-10.93) irrespective of oocyte origin. The higher rate of intensive care unit admittance observed in the IVF group (8.1% vs. 2.4% in the spontaneous pregnancy group) was attributed to preeclampsia (aOR 11.82, 95% CI 5.25-25.87), not to the type of conception. CONCLUSION(S): A high rate of operative delivery was observed in pregnant women infected with SARS-CoV-2, especially in those with IVF pregnancies; method of conception did not affect fetal or maternal outcomes, except for preeclampsia. CLINICAL TRIAL REGISTRATION NUMBER: NCT04558996.
