The Evolution of Head-Upright Tilt-Table Testing in Toronto, Ontario, Canada: 2014-2024.
Article in CJC open, 2025. 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 real-world use of head-upright tilt-table tests (HUTTs) in North America is not known. This single-centre retrospective study in Toronto, Ontario, Canada reports on 1063 HUTTs conducted between 2014 and 2024. Use of the HUTT increased year over year, with a greater increase in HUTTs conducted as a result of a referral diagnosis of postural orthostatic tachycardia syndrome (POTS). Using specific diagnostic criteria for syncope and POTS, patients with either diagnosis who underwent testing, after January 2021 had an almost 50% reduction in the odds of a positive HUTT (syncope: odds ratio: 0.54, 95% confidence interval: 0.40-0.73 and postural orthostatic tachycardia syndrome: odds ratio: 0.51, 95% confidence interval: 0.28-0.95).
