Characteristics and Causes of Stillbirths Following Disruption to Antenatal Care During Implementation of COVID-19 Mitigation Measures.
Article in The Australian & New Zealand journal of obstetrics & gynaecology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
aimRestrictions to mitigate COVID-19 transmission during the pandemic led to the disruption of routine antenatal care. We aimed to assess if those disruptions impacted the rates and types of stillbirths that occurred during that time. MATERIAL AND
methodsWe performed a retrospective cohort study of the types and causes of stillbirths occurring in women attending three maternity hospitals in Melbourne, Australia, to understand if COVID-19 mitigation measures altered them. Stillborn babies conceived between November 2019 and February 2020 (restriction exposed cohort) were compared with stillborn babies conceived between November 2017 and February 2018 or November 2018 and February 2019 (control cohort). Stillbirths were classified according to the Perinatal Society of Australia and New Zealand classification system (2018).
resultsIn the exposed cohort, 29/2511 foetuses were stillborn (11.55 per 1000 births), compared to 53/5171 (10.25 per 1000 births) in the non-exposed cohort. No statistical difference in rates of stillbirth was found between the two groups (odds ratio [OR] 1.13, 95% CI 0.72 to 1.78, p = 0.603). The rate of pregnancy terminations was significantly lower in the exposed cohort (7.1% vs. 34.0%, p = 0.007), while the antepartum stillbirth rate was significantly higher (82.8% vs. 49.1%, p = 0.003), particularly for unexplained stillbirths (51.7% vs. 17.0%, p < 0.001). The rate of congenital abnormalities was lower in the exposed cohort (24.1% vs. 45.3%, p = 0.059), however, not significant.
conclusionsChanges in routine antenatal care during the COVID-19 pandemic may have resulted in a decreased diagnosis of congenital abnormalities, subsequent decreased terminations of pregnancy and a significant increase in unexplained antepartum foetal deaths.
