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

background/purposeOral lichen planus (OLP) is a common chronic inflammatory disease characterized by a T cell-mediated immune response against epithelial cells. The epidemiological survey of OLP in Taiwanese population was scarce. In this study, we investigated the time trend of prevalence stratified by gender, age, urbanization, and income of OLP based on National Health Insurance Research Database (NHIRD). MATERIALS AND

methodsWe studied the claims data of Taiwanese population from NHIRD 1996 to 2013. Patients with the diagnosis of OLP based on the International Classification of Diseases, Ninth Clinical Modification (ICD-9-CM) code: 697.0 were recruited in this study. Demographic characteristics were analyzed by multi-variate Poisson regression.

resultsThe prevalence of OLP increased significantly from 1.3 (per 10

conclusionThe prevalence of OLP in Taiwan significantly increased over the past 18 years. The mean age with OLP was shown in an increased pattern. In addition, OLP occurs more frequently in women than in men.
