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

backgroundOral lichen planus (OLP) is a chronic inflammatory condition of the oral mucosa. Multiple studies have shown that approximately 1% of patients with OLP will develop oral squamous cell carcinoma (OSCC), however, no study has taken a population-based multicenter approach to demonstrate this association. Our main objective was to determine the incidence of OSCC in OLP in a specific population and secondarily to assist physicians regarding appropriate long-term monitoring of patients with OLP.

methodsWe conducted a population-based retrospective cohort study. Patients with OLP from 1986 through 2010 were identified using the Rochester Epidemiology Project (REP) for Olmsted County, Minnesota. For each OLP case (n = 303), we randomly selected two age- and gender-matched referents (n = 606). OLP diagnosis was established based on the World Health Organization (WHO) criteria. Medical records were reviewed for development of OSCCafter the OLP diagnosis (index date). The association between OLP and development of OSCC was assessed.

resultsIn total, 303 patients with incident OLP were identified; the overall incidence of OLP per 100,000 person-years was 11.4 (95% CI, 10.1-12.7). Among the OLP cohort, 7 had OSCC (incidence of OSCC, 3.1%; 95% CI, 0.6-6.4%) at 20 years after OLP diagnosis. Three OSCC cases were identified among the referents. Patients with OLP were 4.8 times more likely to have OSCC than the matched referents. The median time to OSCC development was 14.7 years earlier for the OLP cohort.

conclusionsPatients with OLP, particularly the erosive type, have an increased incidence of OSCC development and should be monitored closely.
