The effect of fetal gender on the biochemical markers of the first-trimester screening.

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
objectivesTo determine the effects of fetal gender on the maternal levels of first-trimester screening biochemical markers, such pregnancy-related plasma protein A (PAPP-A) and beta-human chorionic gonadotropin (β-hCG).
methodsIn this retrospective study, we assessed 267 cases of singleton pregnancies, who underwent first trimester screening tests and delivered between January 2016 and January 2019 at our hospital. Multiple of median (MoM) levels of PAPP-A and free β-hCG, and the neonatal genders according to the birth records were compared and analyzed. Additionally, patients with small for gestational age (SGA) newborns, preeclampsia, and placental ablation, called ischemic placental diseases, were classified into a separate group and their PAPP-A and free β-hCG MoM values and fetal genders were compared.
resultsThere was no significant relationship between the mean values of PAPP-A (1.07±0.6) and free β-hCG (1.23±1.14) and the fetal gender (males: 137, 51.3%; females: 130, 48.7%), respectively (
conclusionPregnancy-related plasma protein A and free β-hCG values were not affected by the fetal gender. However, the significant relationship observed between free β-hCG MoM levels and fetal gender in patients with ischemic placental diseases suggests the need for larger studies on this topic.
