Diagnostic Accuracy of Cartridge Based Nucleic Acid Amplification Test (CBNAAT) in Stool Samples in Pediatric Tuberculosis.
Article in Indian journal of pediatrics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
objectivesTo find out the diagnostic accuracy of stool Cartridge-based nucleic acid amplification test (CBNAAT) as an alternate method as compared to CBNAAT in gastric aspirate (GA) samples in pediatric tuberculosis (TB).
methodsThis cross-sectional study was performed at Department of Pediatrics of a tertiary care hospital. Children aged 0-18 y diagnosed as presumptive tuberculosis were consecutively enrolled. Gastric aspirate and corresponding stool sample was subjected to CBNAAT and its performance was compared in both samples using appropriate statistical tests.
resultsTotal 100 patients were enrolled in the study. Diagnostic accuracy of CBNAAT was 81% and 80% in gastric aspirate and stool sample respectively. On comparing gastric aspirate with corresponding stool sample there was 97% agreement, with Cohen's kappa value of 0.94. There was a statistically significant association observed between gastric aspirate CBNAAT and stool CBNAAT p <0.001 using chi square test. Sensitivity of gastric aspirate CBNAAT and stool CBNAAT was 75% and 73% respectively and specificity was 100% for both the samples compared against Composite Reference Standard (CRS).
conclusionsThe diagnostic accuracy of stool CBNAAT is comparable to GA CBNAAT in children and can be used as a good alternative to gastric aspirate for diagnosis of pulmonary and disseminated tuberculosis in children.
