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

backgroundPrevious analysis showed that the incidence rates of skin cancer in Singapore increased from 1968 to 2006, especially among older Chinese, and particularly for basal cell carcinoma (BCC).

objectiveWe updated the skin cancer incidence rates and time trends among the Chinese, Malays, and Indians in Singapore.

methodsWe analyzed the skin cancer incidence from the nationwide Singapore Cancer Registry from 1968 to 2016.

resultsAmong 12,692 cases diagnosed from 1968 to 2016, there were 8367 (65.9%) cases of BCC, 3598 (28.3%) of squamous cell carcinoma (SCC), and 727 (5.8%) of melanoma. The mean ages at skin cancer diagnosis were 72.7 years for SCC, 66.9 years for BCC, and 59.8 years for melanoma. Sun-exposed areas accounted for 81.3% of BCCs, 61.6% of SCCs, and 26.7% of melanomas. The age-standardized incidence rate of cutaneous BCC was highest in the Chinese and increased by 2.5 fold over the study period, followed by a lower rate and slower increase in the Malays, and the lowest rate among the Indians. The SCC and melanoma incidences remained low in all 3 ethnicities during this study period. The Chinese had the highest relative risk for developing any skin cancer (

conclusionIncidence rates of BCC have increased in Singapore, especially among the Chinese, in the past 5 decades. The SCC and melanoma incidence rates remained low and stable.
