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

introductionAlthough the rising worldwide incidence of thyroid cancer (TC) has been largely attributed to changes in diagnostic means, the full spectrum of contributing factors remains unknown. We present a comprehensive registry-based study evaluating the impact of occupational background on the risk of TC in the Nordic countries.

methodsData were from the Nordic Occupational Cancer (NOCCA) study from the Nordic countries from 1961 to 2005. Standardized incidence ratio (SIR) of TC in each occupational category was calculated using national incidence rates as reference.

resultsThe NOCCA cohort includes 14.9 million people (7.5 million women (50.3%), 7.4 million men (49.7%)). In total, 23,241 TCs were recorded: 16,758 (71.9%) in women and 6483 in men. Increased SIRs were observed in female farmers (SIR 1.19; 95% CI 1.07-1.30) and male fishermen (1.32;1.06-1.62), military personnel (1.29; 0.99-1.66), and clerical workers (1.19; 1.05-1.35).

conclusionOur results suggest an association between certain occupational backgrounds and TC. These findings may help elucidate new risk factors for TC to enable targeted diagnosis and surveillance of individuals most at risk.
