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

backgroundCongenital cytomegalovirus (CMV) is an important cause of neurological problems, particularly sensorineural hearing loss, but data on long-term sequelae and the impact of nonprimary maternal infection are limited. We report updated findings on childhood outcomes from 2 large prospective studies.

methodsPregnant women in Malmö, Sweden, and London, United Kingdom, were included between 1977 and 1986, and newborns were screened for CMV (virus culture of urine or saliva). Cases and matched controls underwent regular, detailed developmental assessments up to at least age 5 years.

resultsOne hundred seventy-six congenitally infected infants were identified among >50 000 screened (Malmö: 76 [4.6/1000 births]; London: 100 [3.2/1000 births]); 214 controls were selected. Symptoms were recorded in 11% of CMV-infected neonates (19/176) and were mostly mild; only 1 neonate had neurological symptoms. At follow-up, 7% of infants (11/154) were classified as having mild, 5% (7/154) moderate, and 6% (9/154) severe neurological sequelae. Four of 161 controls (2%) had mild impairment. Among children symptomatic at birth, 42% (8/19) had sequelae, versus 14% (19/135) of the asymptomatic infants (P = .006). All moderate/severe outcomes were identified by age 1; mild sequelae were first identified at age 2-5 years in 6 children, and age 6-7 years in 3. Among the 16 children with moderate/severe outcomes, 2 had mothers with confirmed and 7 with presumed nonprimary infection.

conclusionsModerate or severe outcomes were reported in 11% of children with congenital CMV identified through population screening, all by 1 year; all impairment detected after this age was mild. Nonprimary infections contributed substantially to the burden of childhood congenital CMV disease.
