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
aimPrenatal maternal infections may impair infant brain development. This study investigated the effect of maternal infections with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during pregnancy on infant neurodevelopment by assessing general movements (GMs).
methodsInfants were recruited for this multicenter prospective cohort study from LMU University Hospital sites in Munich after birth or during routine visits. GMs were recorded and assessed between 1 July 2022 and 31 January 2023, using the Hadders-Algra method. Odds ratios for abnormal GMs were calculated for infants with parent-reported prenatal SARS-CoV-2 exposure compared to unexposed controls. Specific GM subgroups were analysed at preterm, writhing, and fidgety ages.
resultsThe study comprised 114 exposed infants (55.3% male) and 92 controls (54.3% male). There were no significant differences between the groups at birth. Two of the mothers were infected twice and one of them required hospitalisation. GMs were assessed at a mean corrected age (CA) of 4 weeks. The odds ratios showed no significant differences in GM quality between exposed infants and controls in either the total group or the subgroups.
conclusionPrenatal exposure to SARS-CoV-2 did not affect early neurodevelopment, which was determined by GM quality. Further studies should include long-term outcomes.
trial registrationThe study was registered at the German Clinical Trial Register (ID: DRKS00029247; https://drks.de/search/de/trial/DRKS00029247).
