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: We investigated trends in acute respiratory illnesses and influenza activity in Singapore throughout the COVID-19 pandemic. Methods: Publicly available data from the Ministry of Health, Singapore was used to estimate the number of daily acute respiratory illnesses (ARI) and influenza cases between 2019 and Jun 2023. Overseas travel activity was obtained from the Department of Statistics, Singapore. Trends in ARI and influenza activity during different phases of the COVID-19 pandemic with changes in key public health measures were compared. Results: Pre-pandemic influenza activity exhibited seasonal peaks in Jan and Jul, with daily estimated cases exceeding 40 during these periods. During the early pandemic, influenza cases declined sharply to close to zero and remained at these levels until mid-2022, even after public health measures were eased. ARI cases followed a similar initial decline but gradually returned to pre-pandemic levels by 2023, with peaks occurring outside the usual seasonal pattern. These trends corresponded with phases of public health measures, including mask-wearing and travel restrictions. Conclusion: Several hypotheses for these contrasting trends were explored, including increased public health awareness, higher influenza vaccination rates, and potential virus-virus interactions.
