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

backgroundLung cancer is the leading cause of morbidity and mortality worldwide. Small cell lung cancer (SCLC) has been determined to be the most lethal lung malignancy. Few studies have previously analyzed the epidemiological characteristics of SCLC in China. This study analyzed the epidemiological characteristics of SCLC aiming to provide a reference for the prevention of SCLC in Hebei Province.

methodsThe epidemiological characteristics of SCLC using lung cancer data based on population and hospital cancer registries in Hebei Province between 2008 and 2017 were analyzed.

resultsThe proportion of both population- and hospital-based SCLC cases displayed a significant increasing trend. Moreover, the proportion of males was higher than that for female based on population- and hospital-based cases. The proportion of hospital-based SCLC cases in counties was higher than that in cities, whereas there were no significant regional differences between cities and counties based on population. The proportion of both population- and hospital-based SCLC cases decreased consistently with increasing age. There was a difference between population- and hospital-based distribution of subcategories of SCLC.

conclusionsSignificant increases in the proportion of both population- and hospital-based SCLC cases over recent years, particularly in males and in patients aged over 55 years, were observed. Research on the pathogenesis of SCLC in these patients and prevention is urgently required.
