Comparative analysis of diagnostic efficacy of loop-mediated isothermal amplification (LAMP) and CBNAAT in children with suspected tubercular meningitis: a cross-sectional study.
Article in BMJ paediatrics open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Tuberculous meningitis (TBM) poses a diagnostic challenge in children. The available conventional diagnostic methods have low sensitivity. Cartridge-based nucleic acid amplification test (CBNAAT) requires suitable infrastructure and technical expertise. TB loop-mediated isothermal amplification (LAMP) is being increasingly used for the diagnosis of TBM. Few studies have been done in children. We compared the diagnostic efficacy of CBNAAT and LAMP in 50 cases of clinically suspected TBM. LAMP had higher sensitivity (62.50%) but lower specificity (84.62%) than CBNAAT (sensitivity 41.67% and specificity 100.00%). The two tests have moderate agreement with a Cohen's kappa value of 0.48. LAMP is a rapid and sensitive test for resource-limited settings.
