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

Previous studies have demonstrated a higher prevalence of keratinocyte carcinomas (KC) on sun-exposed areas, particularly for squamous cell carcinoma (SCC) compared to basal cell carcinoma (BCC). Few studies in the United States (US) have compared the prevalence of BCC to SCC by anatomical location. The aim of this study was to determine the KC prevalence in a Midwestern US population standardised by relative tumour density (RTD) per anatomical area, which has not been previously reported in the US. Data was collected from Veterans Affairs' patients with biopsy-proven KCs from October 1999 to September 2020. KCs were divided into BCCs and SCCs. RTD was calculated by standardising frequency of occurrence in a location by body surface area. The proportion of BCCs to SCCs for each location was also analysed. A total of 31 663 KCs (17 776 BCCs and 13 887 SCCs) were identified in 10 933 patients, with the majority on the head and neck. BCCs were more likely overall on the trunk and upper arms than SCCs. SCCs were more common on the hands, forearms, genitals/perineum/perianal area, and ears. Both BCC and SCC occurred more frequently over sun-exposed areas when controlling for body surface area of the location. Higher proportions of BCCs were found on sun-protected areas when compared to SCCs. The relative preponderance of SCCs on the genitals/perineum/perianal area may be due to human papillomavirus.
