Technique for Difficult Wharton's Duct Cannulation.
Article in OTO open. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
The comparative ease of cannulating Stensen's duct is contrasted by the acknowledged difficulty in cannulating Wharton's duct. Although access to Wharton's duct can be facilitated with a floor-of-mouth incision, it is desirable to avoid this open approach. We present a technique emphasizing the use of a tapered 4-0 Prolene suture to cannulate Wharton's duct. This guide directs placement of a 26-gauge angiocatheter through a modified Seldinger technique. The suture guide is then removed to permit infusion of saline with expansion of the duct to allow for passage of a 0.38-mm guidewire and progressive dilation with a 24- and 22-gauge angiocatheter over the larger guidewire. This technique was successful in all 4 patients who had difficult access to Wharton's duct. One of these patients also underwent successful cannulation of Bartholin's duct. This novel technique for cannulation of Wharton's duct offers an alternative approach for patients with challenging anatomy.
