Child's Temperament as Risk Factor for Preoperative Anxiety-A Secondary Analysis of the ALPAKA Trial.
Trial report in Paediatric anaesthesia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPreoperative anxiety is common in young children and may impair cooperation during anesthesia induction. Some temperament traits have been associated with higher anxiety levels in the preoperative phase. While midazolam is widely used for anxiolysis, individual responses vary and may be influenced by underlying psychological characteristics such as temperament.
aimsThis study aimed to examine the association between specific temperament traits and preoperative anxiety in young children and to determine whether these associations persist after midazolam administration.
methodsThis secondary analysis of the ALPAKA trial examined associations between temperament and perioperative anxiety in children aged 2-8 years undergoing elective surgery. Temperament was assessed using the parent-reported Integrative Child Temperament Inventory (ICTI). Anxiety was rated at two time points before (T1) and after (T2) midazolam administration using the modified Yale Preoperative Anxiety Scale-Short Form (mYPAS-SF). Additional variables included the Strengths and Difficulties Questionnaire (SDQ) scores, baseline characteristics and prior emotional distress. Spearman correlation (r
resultsEighty-nine children were included in the final analysis. Behavioral inhibition was associated with anxiety at both T1 (r
conclusionBehavioral inhibition is a robust predictor of perioperative anxiety in young children, both before and after midazolam administration. Brief screening for inhibition may help identify children at increased risk and guide individualized, risk-adapted strategies in pediatric anesthesia.
