Validation of the Hindi version of Trivandrum Development Screening Chart (TDSC) as a Developmental Screening Tool in Children aged 1-30 Months.
Article in Indian pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo determine the diagnostic accuracy of Hindi version of Trivandrum Development Screening Chart (TDSC) for developmental screening of children aged 1 - 30 months.
methodsChildren aged 1 to 30 months who were accompanied by their mothers were recruited from the pediatrics department. Children with acute illnesses which could interfere with developmental assessment, unavailable birth records and from families unable to understand Hindi language were excluded. After translation into Hindi, TDSC was piloted initially on 25 children and later on 224 participants by a researcher who was trained in application and interpretation of TDSC. The results were interpreted as item 'Pass' or 'Fail'; 'TDSC delay' or screen positive was considered even with one item fail. Subsequently, Developmental Assessment Scale for Indian Infants (DASII) was administered to all by a trained clinical psychologist as reference tool and the final diagnosis was made based on developmental quotient (DQ) as: 'any delay' (DQ < 85), 'developmental delay' (DQ < 70), 'borderline delay' (DQ 71-84) or 'no delay' (DQ ≥ 85).
resultsThe sensitivity and specificity of Hindi version of TDSC for 'Developmental delay' and for 'Any delay' was 92.3% and 83.6%, and 70.5% and 90.2%, respectively. The test-retest and inter-observer validity was good (Cohen's Kappa 0.720).
conclusionThe Hindi version of TDSC had acceptable psychometric properties and excellent test-retest and inter-rater reliability. Trial registration CTRI/2021/06/033957.
