Cerebral palsy and perinatal mortality in children born in Norway to immigrant mothers.
Article in Developmental medicine and child neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
aimTo compare the prevalence and clinical characteristics of cerebral palsy (CP), and perinatal mortality, in children born to non-immigrant mothers with children born to immigrant mothers.
methodThis was a registry-based cross-sectional study. Data on children born from 2000 to 2016 were extracted from the Medical Birth Registry of Norway and linked to the Norwegian Quality and Surveillance Registry for Cerebral Palsy. The mother's country of birth was categorized into three groups: non-immigrant (born in Norway); immigrant from high-income countries (HICs); and immigrant from low- and middle-income countries (LMICs) (born abroad giving birth in Norway). Birth prevalence of CP and prevalence of perinatal mortality per 1000 live births were calculated. Odds ratios (ORs) for CP among live-born children of non-immigrant mothers compared to mothers from HICs and LMICs were calculated using logistic regression, both unadjusted and adjusted for each risk factor for CP. Pearson χ
resultsThe prevalence of CP among non-immigrant mothers was 2.11 per 1000 live births, 1.44 among mothers from HICs, and 1.71 among mothers from LMICs. The OR for CP in mothers from HICs was 0.68 and 0.81 in mothers from LMICs. Despite mothers from LMICs having higher proportions of consanguinity and lower folate intake, and their children having lower Apgar scores, the ORs for CP were unchanged after adjusting for these. Yet, children born to mothers from LMICs had higher perinatal mortality; their children with CP had higher proportions of intellectual disability.
interpretationThe lower birth prevalence of CP among children born to mothers from LMICs was unexpected. Yet, children born to mothers from LMICs had higher perinatal mortality, which could impact the number of live-born children with CP.
