Establishment of Normative Data for Autonomic Function Tests in Indian Population.
Article in Annals of Indian Academy of Neurology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Background: Normative data for autonomic function tests (AFT) is not available for Indian population. Objective: The aim of the study was to establish normative data in AFT and its correlation with age, gender, and body mass index. Material and Methods: The study was done on 254 healthy subjects of age ≥18 years. All AFTs were done in autonomic laboratory at the Department of Neurology, Christian Medical College and Hospital, Ludhiana. Cardiovascular tests (heart rate response to deep breathing, HR changes in Valsalva maneuver and head-up tilt test (HUT)) and quantitative sudomotor axon reflex testing (QSART) were performed in all the subjects. Fifty subjects underwent thermoregulatory sweat test (TST). Results: The mean age (SD) of study participants was 43 (16.0) years (range 20-84), and 129 (50.8%) were men. The normative value range (2.5-97.5 percentile) for HR difference, E: I ratio, and Valsalva ratio (VR) was 3.5-47.0, 1.05-1.93, and 1.11-2.64, respectively, for all the subjects. HR difference and E: I ratio showed an significant inverse relation with age ( Discussion and Conclusion: Normative AFT data has been established for Indian population for the first time. The values are comparable to previously published studies.
