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.

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.

Abstract

backgroundSmokers are eligible for lung cancer screening using low dose CT (LDCT) if they have a sufficiently high risk of lung cancer. In England, for example, people are eligible if their estimated risk using either of two validated models (PLCO

methodsSUMMIT is a prospective cohort study of a LDCT screening service. We evaluated the impact of cigars, pipes, and cigarillos on lung cancer risk.

resultsAmong 13,000 participants who were current/former cigarette smokers, 511 (1 in 25) were also regular users of cigars, pipes, or cigarillos. The 5-year cumulative lung cancer incidence in people who currently smoked both types of tobacco products was 8.85%, versus 5.74% for cigarette only current smokers. Among these 511 participants, the percentage whose risk was below the screening eligibility threshold ignoring other tobacco products which then exceeded the threshold including these products was 0.6% using LLPv2, and 8.2% using PLCO

conclusionsAll tobacco consumption should be considered when determining screening eligibility to avoid missing those who can benefit from LDCT. CLINICAL
