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
purposeThe primary aim was to conduct a longitudinal pharmacoepidemiological study on the dispensing patterns of the influenza and pneumococcal vaccines in a section of the private healthcare sector in South Africa in the presence of the COVID-19 vaccine to document the dispensing of these two respiratory vaccines alongside COVID-19 vaccines.
methodsA quantitative cross-sectional pharmacoepidemiological study on health insurance data covering 5 years (2017-2021) was conducted. The study population consisted of approximately 3.8 million individuals. Profile analysis was used to compare annual dispensing patterns of both vaccines. Ethical approval for the study was obtained.
resultsThe annual dispensing patterns of the pneumococcal and influenza vaccines differed significantly for the period 2017-2021 (p-value < 0.01), with the influenza vaccine dispensed most frequently from March to June. A similar pattern was observed for both the pre-COVID-19 period (2017-2019) (p-value < 0.01) and the post-COVID-19 period (2020-2021) (p-value < 0.01). At the 5% level of significance, there was a slight increase in the dispensing pattern of pneumococcal vaccines post-COVID-19, when compared to the dispensing pattern pre-COVID-19 (p-value < 0.05). For the period March to June, there was, however, a significant increase in the dispensing pattern of influenza vaccines post-COVID-19 (p-value < 0.01).
conclusionsThe presence of the COVID-19 vaccine has collectively not had a significant impact on the dispensing patterns of pneumococcal and influenza vaccines. When considering the vaccines separately, however, for the months between March and June, significantly more influenza vaccines were dispensed post-COVID-19.
