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

objectivePrevious work has shown the chemosensory dysfunction item of the 22-item Sinonasal Outcome Test (SNOT-22) that assesses problems with "taste/smell" has poor psychometric performance compared with other items on the SNOT-22, which we have hypothesized is due to the simultaneous assessment of two different senses. Our aim was to determine whether distinct smell and taste items in the SNOT-22 would improve psychometric performance.

methodsOne hundred and eighty-one CRS patients were recruited and completed the SNOT-22. Additional items querying problems with the senses of "smell" and "taste," using the same response scale and recall period were given to study participants. Item response theory (IRT) was used to determine IRT parameters, including item discrimination, difficulty, and information provided by each SNOT-22 item.

resultsConfirming previous studies, the chemosensory item of the SNOT-22 (reflecting "taste/smell") had poor psychometric performance. Use of a distinct smell or taste item instead of the combined "taste/smell" item did not improve psychometric performance. However, a dedicated smell question resulted in a left shift of threshold parameters, showing that the dedicated smell item better captures moderate CRS disease burden than the original taste/smell item of the SNOT-22, which by virtue of near-identical IRT parameters appears to more greatly reflect problems with taste.

conclusionsA dedicated smell- or taste-specific item, rather than the combined "taste/smell" item currently in the SNOT-22 does not provide significantly greater psychometric performance. However, a dedicated smell item may better capture moderate CRS disease burden compared with the current chemosensory item on the SNOT-22. Laryngoscope, 132:1644-1651, 2022.
