Adverse Birth Outcomes Associated With SARS-CoV-2 Infection Among Pregnant Women With and Without HIV: A Longitudinal Cohort Study.
Article in Journal of acquired immune deficiency syndromes (1999), 2026. 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
backgroundCOVID-19 and HIV infection are independently associated with increased risk of adverse pregnancy outcomes. However, there is limited evidence on the effect of SARS-CoV-2 infection during pregnancy in sub-Saharan Africa, particularly among women living with HIV (WLWH).
settingTwo antenatal clinics in southern Malawi (2018-2022).
methodsWe conducted a prospective cohort study of singleton pregnancies enrolled at 20-36 weeks gestation. SARS-CoV-2 infection was determined through serologic testing at enrollment and delivery. Participants were enrolled based on HIV status and viral suppression: (1) WLWH with detectable viral load (VL), (2) WLWH with undetectable VL, and (3) HIV-negative women. We used a multivariable logistic regression with adjustment for confounding to evaluate the effect of SARS-CoV-2 alone or in combination with HIV infection on the following adverse birth outcomes: low birth weight (LBW), preterm birth, small-for-gestational-age (SGA), and stillbirth or early neonatal death.
resultsAmong 905 pregnant women, 29% tested positive for SARS-CoV-2, 87% of infections were mild or asymptomatic. Overall, SARS-CoV-2 infection was significantly associated with SGA births (adjusted OR [aOR]: 1.49, 95% CI: 1.03 to 2.13) but not associated with other adverse outcomes. Among WLWH, SARS-CoV-2 was significantly associated with increased odds of LBW (aOR: 2.07, 1.10 to 3.91) and SGA births (aOR: 1.73, 1.01 to 2.91). The effect of SARS-CoV-2 infection among WLWH did not differ based on VL.
conclusionsSARS-CoV-2 infection during pregnancy was associated with adverse birth outcomes, particularly among WLWH. These findings underscore the need for integrated antenatal care and targeted infection prevention strategies for pregnant women with HIV in high-burden settings.
