Review in European archives of oto-rhino-laryngology : official journal of the European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino-Laryngology - Head and Neck Surgery, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04710394 (Efficacy of Bimodal Visual-Olfactory Training in Participants With COVID-19 Resultant Hyposmia or Anosmia Using Participant-Preferred Scents), which is not on this map.

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.

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.

Abstract

Developed in the 1990 s, the "Sniffin 'Sticks" test for the assessment of olfactory threshold, odor identification and discrimination has become a widely used tool both in clinical and research settings. Originally pencil-and-paper documented, it may now be applied using a computer program. The "Filemaker" based software "OLAF" guides the examiner through any user-defined arrangement of the test battery, stores all data in a database, and offers results sheets to be printed out for convenience. The royalty-free program may be downloaded from http://www.tu-dresden.de/medkhno/riechen_schmecken/olaf.zip as a runtime solution application. It is currently available in four languages (English, French, German, and Italian) which can be toggled by a single mouse click, and is suitable for Windows as well as Apple platforms. In conclusion, the currently described software is expected to further facilitate and standardize olfactory testing with the "Sniffin' Sticks" test battery.
