Congenital cytomegalovirus diagnosis: healthcare claims data of linked pregnant people-infant pairs, United States, 2018-2023.

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
objectiveTo describe maternal demographics and compare clinical characteristics of infants with congenital cytomegalovirus (cCMV) identified through diagnostic codes and laboratory data in the United States during 2018-2023.
methodsWe used a CDC-licensed subset of HealthVerity data, which contained linked pregnant people-infant claims data from publicly and privately insured individuals during 2018-2023 (2023 Quarter 3 HealthVerity Maternal Outcomes Masterset data). We identified infants with cCMV using diagnostic codes or positive laboratory test results within 45 days of birth.
resultsAmong 744 (4.6 per 10,000 live births) infants with cCMV during 2018-2023, 599 (81%) were identified by a diagnostic code only. Among 732 linked pregnant people, 91 (12%) had a diagnosis of CMV infection during pregnancy, with a similar distribution by age group and insurance type, but a lower proportion were Black as compared to those without CMV infection during pregnancy (14% vs. 29%, respectively). Overall, 452 (61%) infants had ≥1 cCMV-related clinical sign at birth and 185 (25%) had valganciclovir prescriptions. Eighty-eight (68%) infants identified by a positive laboratory test only had no cCMV-related signs and none had valganciclovir prescriptions.
conclusionsUsing healthcare claims data, we found a minimal overlap of cCMV identified by diagnostic codes and laboratory test results. A minority of linked pregnant people with infants with cCMV had a CMV diagnosis during pregnancy. cCMV surveillance will help better understand the validity of ICD codes to identify infants with cCMV, describe the spectrum of disease, and monitor the use of antivirals.
