Mode of conception does not appear to affect placental volume in the first trimester.
Article in Fertility and sterility, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
objectiveTo study whether infertility treatments, including IVF and non-IVF fertility treatments, are associated with diseases of placental insufficiency in early gestation. First trimester placental volumes by ultrasound and chorionic villi weight during sampling (CVS) were performed to detect differences between pregnancies conceived spontaneously versus with fertility treatments.
designRetrospective cohort.
settingAcademic tertiary center. PATIENT(S): Women with singleton pregnancies undergoing CVS and first trimester ultrasound from April 2007 to November 2015. INTERVENTION(S): Estimated placental volume (EPV) was calculated from ultrasound images using a validated computation and CVS estimated tissue weight was performed using a validated visual analogue scale. MAIN OUTCOME MEASURE(S): Adjusted linear regression was used to compare EPV and CVS weight based on mode of conception. RESULT(S): A total of 1,977 spontaneous and 334 conceived with fertility treatments (133 non-IVF and 201 IVF) pregnancies were included. Significant differences in maternal age, gravidity, hypertension, and smoking status were identified. EPV and CVS weight were correlated with maternal age, gestational age, and maternal hypertension. Adjusted linear regression showed no difference in EPV in pregnancies conceived with fertility treatments versus spontaneously. The CVS weight was significantly lower in the IVF conceptions in unadjusted univariate analyses. However, after adjusted regression, this was no longer significant. CONCLUSION(S): Mode of conception does not appear to affect first trimester placental size. As differences in maternal age, hypertension, and smoking status differ among the groups and are correlated to placental size, it may be the underlying patient population leading to abnormal placentation and insufficiency, not the fertility treatments used.
