Invasive Pneumococcal Diseases Before and After the COVID-19 Pandemic in Italy (2018-2023).
Article in Microorganisms, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study assessed the epidemiological and microbiological invasive pneumococcal disease (IPD) changes that occurred before and after the emergence of COVID-19 in Italy. All IPD cases reported through the nationwide surveillance system during 2018-2023 were included. IPD incidence and serotype distributions were analyzed by age group. IPD incidence in 2020-2021 declined in all age groups compared with 2018-2019, especially in children less than 2 years of age and elderly people aged > 64 years. A resurgence of IPD cases was observed from late 2022 onwards, with values in children exceeding those seen before the pandemic. The post COVID-19 increase in children was mainly driven by some PCV13 serotypes, such as 3, 19A, and 19F, but also non-vaccine serotypes, including 10A, 8, and 24F, while in the elderly population, a predominance of serotypes 3 and 8 was observed. In conclusion, a steep drop in IPD incidence was observed during the peak of the COVID-19 pandemic, followed by a subsequent upsurge of cases, especially in children. Continuous national surveillance is necessary to monitor the dynamics and evolution of IPD and the impact of new higher-valency vaccines in Italy over the next few years.
