Evaluation of Olfactory Function in Asymptomatic Children With Congenital Cytomegalovirus Infection.
Article in Cureus, 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 aim Congenital cytomegalovirus (cCMV) is the most prevalent congenital infection worldwide, associated with numerous long-term sequelae, even in infants asymptomatic at birth. However, data are lacking for asymptomatic-at-birth children, who account for the majority of cases. Thus, the aim of the study was to evaluate the olfactory function of asymptomatic cCMV-infected children and compare it to matched healthy controls using a validated odor Identification test. Methods A case-control study was conducted. Asymptomatic cCMV-infected children and healthy controls without cCMV history over the age of five were included. Cases and controls were matched at a 1:2 ratio for age and sex. Exclusion criteria included other conditions associated with transient or permanent olfactory dysfunction. A U-Sniff odor identification test (Kids Ident Test "U-Sniff"; Burghart Messtechnik GmbH, Holm, Pinneberg, Germany) was used to evaluate olfaction. Statistical analysis was conducted using IBM SPSS Statistics for Windows, version 25.0 (IBM Corp., Armonk, New York, United States). Results Overall, 63 children were included (61.9% females; median age: 7 years). No differences in olfactory function (p=0.657) or olfactory score percentile (p=0.853) were detected between cases and controls. No differences in olfactory function or olfactory score percentile were detected in two sub-analyses, where participants were stratified according to age group (5-8 years old; p=0.545 and p=0.472, respectively, and 9-11 years old; p=1.000 and p=0.088, respectively) and COVID-19 infection history (positive history; p=0.645 and p=0.694, respectively, and negative history (p=not computable and p=0.509, respectively). Conclusions Olfactory function of children with cCMV infection who were asymptomatic at birth does not seem to differ from healthy sex-and-age-matched controls.
