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: Data on burden of invasive pneumococcal disease (IPD) are lacking from Southeast Asia. With the introduction of higher-valency pneumococcal conjugate vaccines (PCVs), we aim to assess the impact of PCV introduction into Singapore's National Childhood Immunisation Schedule (NCIS) on IPD burden and serotype replacement. Methods: Using IPD surveillance data from a single center, we compared the incidence of IPD in children aged <17 years before and after introduction of the PCV into the NCIS (2000-2009, period 1; 2010-2023, period 2). Results: The overall incidence of IPD from 2000 to 2023 was 3.9 per 100 000 children. The decline in IPD incidence between periods 1 and 2 was greatest in children aged ≤2 years (13.3 to 4.7/100 000 children; incidence rate ratio 0.4 [95% CI, .3-.5]; Conclusions: Introduction of PCV into Singapore's NCIS led to a substantial reduction in IPD burden in children aged ≤2 years. Serotype 19A continues to pose a challenge as a disease-causing serotype after PCV13 implementation in Singapore.
