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

Objective: To assess: (a) associations between prenatal SARS-CoV-2 exposure and early childhood neurodevelopmental outcomes, and (b) whether these varied by infection trimester. Methods: We conducted a systematic review and meta-analysis of observational studies modelling the neurodevelopmental outcomes of children prenatally exposed to SARS-CoV-2 compared to unexposed children. PubMed and PsychInfo were systematically searched from inception to March 2025. Primary analysis was random-effects modelling of overall associations. Secondary analysis assessed variation by trimester via standardised mean differences (SMD). Results: 11 observational studies were included. Overall, there was no statistically significant association between prenatal SARS-CoV-2 exposure and early childhood neurodevelopmental outcomes, both before (odds ratio: 1.08; 95% confidence intervals: 0.82, 1.42) and after (odds ratio: 0.98; 95% CI: 0.81, 1.17) excluding high variance studies. First trimester prenatal SARS-CoV-2 exposure was associated with poorer neurodevelopmental scores (3.87; 95% CI: 3.19, 4.55) than prenatal exposure in the second trimester (6.07; 95% CI: 5.11, 7.03) or third trimester (6.31; 95% CI: 5.54, 7.09). However, this analysis was limited to three studies only, with high heterogeneity between studies. Conclusions: Prenatal SARS-CoV-2 exposure is not associated with early childhood neurodevelopmental outcomes. Future research should keep monitoring associations as more data becomes available. More robust research is required on trimester-specific associations.
