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
purposeThis 3-study paper aimed to develop and validate a self-reported Health-Related Quality of Life Pictorial Inventory for Early Childhood Children (HEALTH-PIC). The scale was designed to overcome existing barriers of parent-proxy response styles such as observation bias and offer an alternative to age-suited literary questionnaires to assess self-reported health-related quality of life, including physical health, emotional health, social health and school health in early childhood.
methodsEach study targeted a specific aspect of scale development, employing distinct samples to refine and validate the inventory. Study 1 involved item development/revision, which utilized a panel of 10 experts (Mean
resultsScale items in Study 1 were developed alongside experts and parents with a strong theoretical and statistical support calculated using Aiken's agreement (Aiken's V p < 0.05), ensuring that the items were clear, accurate and applicable for children. In Study 2, we ensured that primary respondents of different ages were able to accurately identify the pictorial images (Aiken's V p < 0.05) and complete the questionnaire when the scripted instructions were read aloud. In Study 3, structural equation modelling of the HEALTH-PIC demonstrated a robust factor structure (CFI and TLI > 0.99; RMSEA and SRMR ≤ 0.08), concurrent validity, discriminant validity, criterion validity and an acceptable level of internal consistency (i.e., Cronbach's α = 0.60-0.66).
conclusionThe findings of the three studies provide preliminary evidence to support the content validity and construct validity of the HEALTH-PIC. This novel pictorial scale not only provides a reliable and valid assessment of the multidimensional aspects of health-related quality of life among children but can also overcome existing barriers of parent-proxy or age-suited questionnaires.
