Table 2 Responses to clinic blood pressure at screening

From: Trial of Exercise to Prevent HypeRtension in young Adults (TEPHRA) a randomized controlled trial: study protocol

CLINIC BLOOD PRESSURE AT SCREENING RESPONSE
NORMAL
 SBP < 110 & DBP < 70 Complete screening & exclude from trial
POSSIBLE PRE-HYPERTENSION
 110 ≤ SBP ≤ 139 &/or 70 ≤ DBP ≤ 89 Complete screening & conduct 24-h ABP monitoring as appropriate
POSSIBLE STAGE I HYPERTENSION
 140 ≤ SBP ≤ 159 &/or ≤ 90 DBP ≤ 99 In all cases: check for signs of end organ damage (resting 12 lead ECG, urinary spot analysis, retinal imaging) if signs of end organ damage exist, exclude from trial and refer for further assessment
As appropriate:
-complete screening & exclude from trial
-complete screening & refer for further assessment
-complete screening & conduct 24-h blood pressure monitoring
Note: If subsequent 24-h awake ABP > 135/85, review case and consider referral for further assessment
POSSIBLE STAGE II HYPERTENSION
 SBP > 159 Exclude from trial & refer for further assessment
 DBP > 99 Exclude from trial & refer for further assessment
