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

The COVID-19 pandemic had a negative effect on oncology healthcare services in Poland, with a reduction in the national breast cancer (BC) screening program coverage rates. This article analyzes the impact of the pandemic on BC stage at diagnosis in a regional cancer center in Poland. Records from BC multidisciplinary team (MDT) meetings that took place in the years 2019-2021 were gathered. BC clinical staging was compared. Age-related subgroups were additionally analyzed to reflect possible screening program disruptions. The total number of BC cases fell by 8% in 2020 compared with 2019, with a 14% fall in the screening age group. In 2021, a stage shift was observed, with stage II BC becoming most frequently diagnosed (as opposed to stage I BC in 2019 and 2020). A statistically significant increase in the number of stage III BC cases was observed in 2021.
