1 · What the graph read from 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.

2 · The registry

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

Background: Non-typeable Methods: A systematic search of PubMed, Scopus, Web of Science, Google Scholar, and ScienceDirect was conducted up to May 2025. Eligible studies reporting NT-Sp carriage, molecular typing, or AMR profiles were included. Data extraction and quality assessment followed PRISMA guidelines. A meta-analysis was performed to estimate pooled prevalence of NT-Sp carriage and resistance, with subgroup and meta-regression analyses exploring heterogeneity. Methodological quality was assessed using the Newcastle-Ottawa Scale adapted for cross-sectional studies. Only open-access and free full-text articles were included, which may have introduced selection bias. Results: Forty studies from 23 countries were included. The pooled NT-Sp carriage prevalence was 4.64% (95% CI: 2.78%-6.92%), with substantial heterogeneity ( Conclusion: NT-Sp is a globally distributed and genetically diverse pneumococcal subset with considerable AMR potential. Its persistence post-PCV introduction and resistance gene carriage highlights the need for improved detection, molecular surveillance, and consideration in next-generation vaccine development. Specifically, clinical laboratories in high-prevalence settings should adopt molecular methods (e.g., PCR or WGS) to detect NT-Sp in carriage surveillance; empirical antibiotic guidelines for pediatric respiratory infections should consider NT-Sp resistance patterns, particularly the high prevalence of co-trimoxazole resistance (67%) and next-generation PCV trials should include NT-Sp carriage as an exploratory endpoint. Integrating NT-Sp into global pneumococcal control strategies is essential.
