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 AND
objectivesSkin diseases can greatly impair quality of life (QoL) of pediatric patients and their families. The Infants and Toddlers Dermatology Quality of Life questionnaire (InToDermQoL) is the first skin-generic instrument assessing QoL in children ≤ 4 years, as reported by their caregiver. This study aimed to psychometrically validate the German version of the InToDermQoL. PATIENTS AND
methodsThe psychometric properties of the InToDermQoL were examined in a sample of 148 children with various skin diseases (age groups [n]: < 1 [44]; 1-2 [68]; 3-4 [36]).
resultsExploratory factor analysis suggested a unidimensional structure of the version for children < 1 year, and a two- and three-factor structure for the two older age groups, respectively. Internal consistency was excellent (Cronbach's alpha, 0.904-0.922). Two-week test-retest reliability was good, except in children aged 1-2 years (intraclass correlation coefficient [ICC], 0.430). The InToDermQoL demonstrated good convergent validity with other QoL questionnaires.
conclusionsThe German InToDermQoL is a valid and reliable QoL measure in children ≤ 4 years with any skin disease. Application of the tool in research and clinical practice will contribute to a better understanding of the impact of pediatric dermatoses, and optimize care and support for affected families.
