Risk analysis of tooth extraction in hypertensive patients under ECG monitoring: a single-center retrospective study.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
objectivesThis study aimed to identify risk factors associated with intraoperative hypertension and new-onset electrocardiographic (ECG) abnormalities in hypertensive patients undergoing tooth extraction. MATERIALS AND
methodsThis case-control study included 2,059 cases of tooth extractions performed in hypertensive patients under intraoperative ECG monitoring at Peking University School and Hospital of Stomatology. Blood pressure (BP) and heart rate (HR) were recorded at four key time points. We specifically analyzed patients who required antihypertensive intervention and those with new-onset intraoperative ECG abnormalities, employing logistic regression to identify independent risk factors. Additionally, ROC curves were used to determine the optimal cutoff points for linear variables, thereby developing the most effective predictive model.
resultsA total of 8.01% of patients required temporary intraoperative antihypertensive medication for blood pressure control, while 37.20% exhibited transient intraoperative ECG abnormalities. Only two cases resulted in temporary procedure termination due to inadequate blood pressure control, while all other procedures were successfully completed. Preoperative systolic blood pressure(SBP) ≥ 159 mmHg (AUC = 0.91, Sensitivity = 84.24%, Specificity = 88.75%) and operative time (OR = 3.620, P<0.001) were significantly associated with intraoperative blood pressure fluctuations. In addition, sex (OR = 0.796, P = 0.019), age (OR = 1.024, P < 0.001), history of cerebrovascular disease (OR = 1.301, P = 0.020), SBP at the start of the operation (OR = 1.011, P = 0.006), number of teeth extracted per session (OR = 1.182, P < 0.001), and estimated operative time (OR = 1.236, P = 0.017) were all significantly associated with new-onset intraoperative ECG abnormalities.
conclusionsIntraoperative hypertension was strongly associated with preoperative SBP ≥ 159 mmHg and prolonged operative time. New-onset intraoperative ECG abnormalities were significantly associated with both patient-related factors (age, sex, cerebrovascular disease, baseline BP) and procedural variables (number of teeth extracted, and operative time). CLINICAL RELEVANCE: This study provides evidence-based recommendations for optimizing cardiovascular risk management in hypertensive patients undergoing oral procedures, highlighting the need for individualized monitoring strategies.
