Abdominal-only Compression Garments Reduce Orthostatic Tachycardia and Improve Symptoms in Patients With Postural Orthostatic Tachycardia Syndrome.
Trial report in The Canadian journal of cardiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04881318 (Compression Garments in the Community With POTS), which is not on this 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.

Abstract
backgroundCompression garments are a relatively inexpensive and easy-to-implement treatment, but the longer term benefits of abdominal compression in a real-world setting are not known. In this study we sought to evaluate commercially available abdominal compression garments in a real-world setting in patients with postural orthostatic tachycardia syndrome (POTS).
methodsParticipants completed four 10-minute active stand tests, with and without an abdominal compression garment, in the morning (Test #1: AM-OFF; Test #2: AM-ON) and afternoon (Test #3: PM-ON; Test #4: PM-OFF). Participants held medication that could augment heart rate (HR) and blood pressure during this 1-day study. A Holter monitor was used to record HR and participants recorded their symptoms using the Vanderbilt Orthostatic Symptom Score at the end of each standing test (range 0-90, where 0 = no symptoms). Continuous data are presented as median (25th-75th percentile).
resultsStanding HR (103 [91-114] vs 118 [99-134], P = 0.002) and change in HR with upright posture compared with supine (27 [19-42] vs 41 [26-48], P < 0.001) were reduced, and symptoms improved (29 [16-45] vs 35 [25-60], P = 0.005), during AM-ON compared with AM-OFF. When the garment was removed after several hours of use (PM-ON vs PM-OFF), standing HR (P = 0.04), ΔHR (P = 0.01), and symptoms (P = 0.02) increased.
conclusionsCommercially available abdominal compression garments reduced HR and improved symptoms both acutely and after several hours of use. Abdominal compression garments may provide a good alternative to full waist-high compression garments in patients with POTS. CLINICAL
