Fig. 2From: Prediction of autonomic dysreflexia during urodynamics: a prospective cohort studyCardiovascular parameters during urodynamic investigation by presence of neurogenic detrusor overactivity. Cardiovascular changes in (a) SBP, (b) DBP, and (c) HR in SCI patients who have either presented NDO (right side in dark blue) or not (left side in Maya blue). At the start of UDI, cardiovascular parameters were not significantly different between both groups. In patients with NDO, cardiovascular changes in SBP (44, 95% CI 40.2–48.6 vs. 30, 95% CI 21.1–39.6 mmHg, p = 0.007) and DBP (18, 95% CI 16.3–19.8 vs. 13, 95% CI 9.3–16.6 mmHg, p = 0.016) during UDI were significantly different compared to patients without NDO. Changes in HR (–8, 95% CI –10.0 to –6.4 vs. −4, 95% CI –7.7 to –0.4) did not significantly (p = 0.06) differ between both groups. Each circle represents one patient’s cardiovascular changes during UDI. Error bars represent mean and the 95% CI of cardiovascular changes; i.e., the worse out of two same session UDIs was used.
