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
introductionChildren with speech sound disorders (SSDs) may have difficulties with speech perception and/or phonological awareness. Research on this area remains limited in children who speak tonal languages, such as Thai. This study aimed to investigate whether Thai-speaking preschool children with SSD show difficulties in speech perception and phonological awareness compared to age-matched typically developing (TD) children. The study also examined the relationships among age, speech production, vocabulary abilities, and speech perception and phonological awareness within both SSD and TD groups.
methodsA total of 76 Thai-speaking children (SSD n = 32, TD n = 44) in kindergarten levels 2-3, aged 4;0-6;6 years, participated in this study. All children completed speech and vocabulary assessments, as well as speech perception and phonological awareness experiments. The speech perception experiment included two tasks: (1) phonemic discrimination and (2) lexical and phonetic judgement. The phonological awareness experiment included three tasks: (1) initial phoneme identification, (2) rime awareness, and (3) lexical tone awareness.
resultsChildren with SSD did not perform differently from their TD peers when controlling for age and receptive vocabulary. Age predicted performance on phonemic discrimination and rime awareness in the SSD group, and on lexical and phonetic judgement and rime awareness in the TD group. Receptive vocabulary predicted only rime awareness in the SSD group. Speech production, as measured by percentage consonants correct, was not a significant predictor of performance in either group.
conclusionThe findings provide new evidence on speech perception and phonological awareness performance in Thai-speaking children. Children with SSD did not show difficulties in speech perception or phonological awareness in this study, which may be explained by the mild-to-moderate severity of SSD in these children. This study highlights the need to develop standardised Thai articulation and phonological assessments to facilitate more precise classification of children into specific SSD subtypes in future studies.
