Perinatal characteristics and longer-term outcomes in Brazilian children with confirmed or suspected congenital Zika infection: ZIKAction Paediatric Registry.
Article in Dialogues in health, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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: Despite growing scientific knowledge of Zika virus (ZIKV) infection, questions remain regarding ZIKV infection in pregnancy and congenital ZIKV syndrome (CZS). Methods: The ZIKAction Paediatric Registry is an international registry of children with documented ZIKV exposure in utero and/or with confirmed or suspected CZS. Its aim is to characterize these children (i.e., clinical, radiological, neurodevelopmental features) and describe outcomes, longer-term sequelae and management through retrospective case note review. This analysis described the maternal and perinatal characteristics of children in the Registry's Bahia arm, assessed their neuroimaging, ophthalmic, hearing and electroencephalography abnormalities by microcephaly classification and reported on hospitalisations. Children born in 2015-2018 and enrolled 2020-2021 in three public health facilities in Salvador were included. Results: Of 129 (57% female) children, 15 (11·6%) had laboratory-confirmed congenital ZIKV infection and 114 (88·4%) suspected CZS. At delivery, 15 (11·6%) were normocephalic, 30 (23·3%) moderately microcephalic, and 84 (65·1%) severely microcephalic. Median birth head circumference z-score was -3·51 [IQR, -4·69,-2·73]. During follow-up, all children had abnormal neuroimaging, 80·3% (94/117) abnormal electroencephalogram, 62·2% (77/120) ophthalmic abnormalities, and 27·4% (34/124) hearing impairment. Microcephaly classification was significantly associated with gestational age, and ophthalmological and electroencephalography abnormalities. Of 125 children with hospitalisation data, 52 (41·6%) had been hospitalised by most recent follow-up, at median age of 15·8 [4·0, 34·4] months; infections were the leading cause. Conclusion: Congenital ZIKV infection is an emerging disease with a varied and incompletely understood spectrum. Continued long-term follow-up is essential to understand longer-term prognosis and to inform future health and educational needs.
