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

Human amniotic fluid collected during amniocentesis contains a heterogeneous population of differentiated and undifferentiated cells. Properties and number of these cells vary depending on the gestational age and the presence of potential fetal pathologies. The aim of this study was to analyze the effects of maternal, fetal, and environmental factors on the success rates of amniotic fluid stem cell cultures, the number of human amniotic fluid stem cells (hAFSC), their growth rates in primary cultures, and the number of cell passages. The study included 355 patients qualified for genetic amniocentesis at the Prenatal Genetic Unit, Department of Obstetrics, Gynecology and Oncologic Gynecology, Nicolaus Copernicus University Medical College in Bydgoszcz in 2011-2017. The mean age of the study participants was 34 ± 6.2 years, and mean gravidity amounted to 2.48 ± 1.4. Amniotic fluid sample volume turned out to be a highly significant (
