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

introductionCancers are among the worst noncommunicable diseases around the world. Head and neck cancers are ranked as the fifth most common cancers worldwide. As there are different distributions of risk factors around the world, the incidence of these cancers varies from one place to another. MATERIALS AND

methodsWe conducted a descriptive analytic cross-sectional study, based on census-based records from the private oncology clinic in Mashhad, Iran. Data from 1,075 patients with head and neck cancers were analyzed from 1986 to 2010. We categorized the duration of study into five periods: 1986-1990, 1991-1995, 1996-2000, 2001-2005, and 2006-2010. Head and neck cancers refers to cancers originating from seven sites in the head and neck including the nasal cavity, oral cavity, pharynx, larynx, salivary glands, paranasal sinuses, and thyroid.

resultsData of 1,075 patients were analyzed. 66.2% were male. Mean ± standard deviation (SD) age at the time of diagnosis was 55.37±15.55 years. The most frequent type of head and neck cancer was larynx cancer (36%), followed by pharynx (28.5%), oral (17.5%), thyroid (6.8%), sinus (6.4%), salivary gland (4.10%), and nasal cancer (0.70%). although larynx cancer was the most frequent cancer over the whole study duration, there was a significant (P=0.04) difference in the relative frequency of these cancers across the five time periods. There was a significant difference in mean age between cancer categories (P<0.001). The only cancer with a different mean age at different time periods was pharynx cancer (P=0.02). There was a significant difference between sex and cancer categories (P<0.001).

conclusionLaryngeal cancer was the most common head and neck cancer over the whole duration of this study. The differences in the patterns of other head and neck cancers could be due to geographical differences and also different risk factors and lifestyles all over the world. Further investigations in these fields are suggested in future studies.
