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

backgroundGreater neonatal pain is associated with higher internalizing behaviours in very preterm infants at 18 months corrected age, but it is unknown whether this relationship persists to school age. Moreover, it is unclear whether morphine ameliorates or exacerbates the potential influence of neonatal pain/stress on internalizing behaviours. We examined whether neonatal pain-related stress is associated with internalizing behaviours at age 7 years in children born very preterm, and whether morphine affects this relationship.

methodsOne hundred one children born very preterm (≤32 weeks gestation) were seen at mean age 7.7 years. A parent completed the Parenting Stress Index and Child Behavior Checklist questionnaires. Neonatal pain-related stress (the number of skin-breaking procedures adjusted for clinical factors associated with prematurity) was examined in relation to internalizing behaviour, separately in subjects mechanically ventilated and exposed to both pain and morphine (n = 57) and those never mechanically ventilated, exposed to pain but not morphine (n = 44).

resultsIn the non-ventilated group, higher skin-breaking procedures (p = 0.037) and parenting stress (p = 0.004) were related to greater internalizing behaviours. In the ventilated group, greater morphine exposure (p = 0.004) was associated with higher child internalizing scores.

conclusionsIn very preterm children who undergo mechanical ventilation, judicious use of morphine is important, since morphine may mitigate the negative effects of neonatal pain on nociception but adversely affect internalizing behaviours at school age. Management of procedural pain needs to be addressed in very preterm infants in the neonatal intensive care unit, to prevent long-term effects on child behaviour.
