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
introductionLabour epidural analgesia is the most effective method for intrapartum pain relief and is associated with improved maternal outcomes. However, concerns have been raised regarding potential associations between labour epidural analgesia and adverse psycho-emotional outcomes in children. Evidence from large epidemiological studies is inconsistent and potential biological mechanisms remain unclear. Maternal immune activation during pregnancy may play a role. We aimed to investigate behavioural and psycho-emotional outcomes in children of mothers who received epidural analgesia during labour, accounting for perinatal mental health, sociodemographic characteristics and cytokine profiles.
methodsSingleton vaginal births from the Biology, Affect, Stress, Imaging and Cognition study were included. Child behavioural outcomes were assessed by Child Behavioural Checklist scores at 18 months, 6 years and 11 years postpartum in the U-BIRTH follow-up cohort, with higher scores indicating more behavioural difficulties. The main exposure was maternal use of labour epidural analgesia. Maternal data were collected from questionnaires and medical records.
resultsAmong 1962 mother-child dyads, 726 (37%) received labour epidural analgesia. Younger maternal age; lower resilience; inflammatory diseases; primiparity; antenatal depression; fear of childbirth; and longer duration of labour were associated with higher Child Behavioural Checklist scores at 18 months postpartum. In crude analysis, labour epidural analgesia correlated with higher Child Behavioural Checklist scores at 18 months postpartum; however, this association was not significant after adjusting for confounders. Among those with lower expression of TNFSF14 and CXCL6 cytokines, labour epidural analgesia use was associated with higher Child Behavioural Checklist scores. DISCUSSION: Use of epidural analgesia during labour was not found to be independently associated with adverse child behavioural outcomes. Variations in maternal cytokine profiles among those choosing labour epidural analgesia or not may influence susceptibility to early behavioural differences. Replication in larger cohorts and further exploration of additional immune biomarker dynamics during pregnancy are warranted.
