[Prognostic factors for successful outcome in sialendoscopy for sialolithiasis].
Article in Laryngo- rhino- otologie, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe success of sialendoscopy depends on several factors. The 2008 introduced lithiasis-stenosis-dilatation (LSD) classification intended to describe more precise the stone-duct system. We investigated whether the LSD classification and additional pre- and intraoperative parameters could be used as prognostic factors for success.
methodsWe retrospectively assessed patients with primary sialendoscopy for sialolithiasis between September 2018 und March 2020. Among others, the outcome variables were the stone size, location and LSD classification.
resultsWe included 37 patients. The success group included 12/37 (32 %) patients. The median stone size was 3.7 millimeters (mm) in the success group and 10.0 mm in the failure group (Mann-Whitney test; p < 0.0001). In the success group, 11/12 stones were distal in contrast to the failure group (13/25 stones proximal; Pearson's chi-square test; p = 0.010). We noted 10 L1S0D0 stones in the success group in contrast to the failure group (15 L3aS0D0 stones; Pearson chi-square test; p = 0.001). For distal stones smaller than 5 mm, the success rate was 100 % and for proximal stones larger than 4 mm, it was 0 %. For stones free in the duct lumen (L1S0D0), the success rate was 60-100 %.
conclusionThe distal stone location and the smaller stone size in a normal duct should be beneficial prognostic factors for success. Future studies should focus on the LSD classification, stone volume, stone duct orientation and stone distance from the papilla.
