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

backgroundEndoscopic ultrasonography is a safe and accurate modality for evaluating and managing hepatobiliary and gastrointestinal conditions (malignant and nonmalignant); its use is increasing. The aim of this study was to describe regional trends in the use of endoscopic ultrasonography in Ontario.

methodsWe conducted a population-based retrospective cohort study using health administrative databases. We identified all patients who underwent an endoscopic ultrasound procedure in Ontario from 2003 to 2011 using physician billing data. Patient, physician and institution characteristics were examined. The primary outcome was use of endoscopic ultrasonography.

resultsWe identified 9076 endoscopic ultrasound procedures performed in 8001 patients (3858 women [48.2%]; median patient age at first procedure 59 years). A total of 3066 procedures (33.8%) involved fine-needle aspiration. Use of endoscopic ultrasonography increased 17-fold over the study period. In 2011, people living in the health region with the highest rate of use of endoscopic ultrasonography were more than 4 times more likely to undergo the procedure than people living in the health region with the lowest rate of use (standardized rate 61.6 v. 12.9 per 100 000). About 7 in 10 endoscopic ultrasound procedures were performed in an academic institution or regional cancer centre. All 17 endoscopists performing endoscopic ultrasonography during the study period practised in urban areas.

interpretationAlthough the use of endoscopic ultrasonography increased over time in Ontario, there were marked regional differences in use. Provincial needs- and evidence-based initiatives may be needed to narrow the regional gaps in provision of endoscopic ultrasound services in the province.
