Sex differences in the contribution of blood pressure to acute changes in aortic augmentation index.
Article in Journal of human hypertension, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Augmentation index (AIx), derived from aortic pulse waveform, is related to arterial stiffness and increased cardiac workload. Sex differences were observed in the relationship between blood pressure (BP) and AIx at rest. In addition, positive correlation between BP and AIx in men during a pressor stimulus was observed previously. However, whether BP is important to acute changes of AIx also in women is yet to be investigated. Therefore, we sought to investigate whether there are sex differences on the relationship between BP and AIx. In all, 16 men (age 27 ± 5 yr; height 176 ± 1 cm; weight 77 ± 7 kg; mean ± SD) and 13 women (age 26 ± 5 yr; height 164 ± 0.3 cm; weight 63 ± 7 kg; mean ± SD) underwent 3 min of rest followed by 3 min of cold pressor test (CPT). Heart rate during CPT was similar to rest. CPT increased BP in both groups and the magnitude was similar between groups. AIx and left ventricle energy wasted (E
