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

objectiveSurgical care has been significantly affected by the COVID-19 pandemic. This study was conducted to evaluate the effects of the pandemic on lung cancer and mediastinal tumor surgery.

methodsChanges in the number of surgical procedures for lung cancer and mediastinal tumors were analyzed using the National Clinical Database of Japan. Patient characteristics, including disease stage and histological type, from 2019 to 2022 were evaluated using annual datasets.

resultsComparisons with 2019 showed that the number of patients who underwent surgery for primary lung cancer or a mediastinal tumor decreased in 2020 and then remained stable. There were no clinically significant changes in the trend over the four-year period regarding the number of patients for each clinical and pathological stage of lung cancer. Regarding mediastinal tumors, there was no significant difference in tumor size between years. There was a slight change in the selection of surgical indication during the second quarter of 2020, although its impact on annual trends in the stage distribution for lung cancer and primary disease for mediastinal tumors was minimal.

conclusionsAnalyses of lung cancer and mediastinal tumor surgery cases in Japan during the COVID-19 pandemic showed no significant disease profile changes related to treatment delay.
