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
backgroundDespite adequate blood pressure control, many hypertensive patients remain at risk of cardiocerebral events. This study investigated the relationship between antihypertensive treatment intensity score (TIS) and interankle diastolic blood pressure difference (dIAND), and their utility in risk stratification.
methodsWe analyzed 368 patients with well-controlled hypertension (24-hour ambulatory blood pressure monitoring ≤ 130/80 mmHg), and pre-existing cardiovascular disease. Patients were stratified by median TIS (0.625) into low (TIS1) and high (TIS2) intensity groups. dIAND was calculated as the absolute difference in diastolic pressure between ankles. Patients were followed for 3 years for adverse cardiocerebral events.
resultsDuring follow-up (median 36 months), 73 major events were documented. The high TIS group exhibited significantly higher event rates (25.8 vs. 14.6%, log-rank P = 0.021), and remained an independent predictor after multivariable adjustment [adjusted hazard ratio: 1.92, 95% confidence interval (CI): 1.07-3.45, P = 0.027]. A modest correlation was observed between TIS and dIAND ( r = 0.26, P < 0.001). Patients with dIAND ≥15 mmHg had higher event rates (35.0 vs. 18.0%; P = 0.015); this association was attenuated in multivariable models. Notably, the combination of high TIS and elevated dIAND identified a subgroup with a 3.22-fold increased risk (adjusted hazard ratio: 3.22, 95% CI: 1.51-6.85, P = 0.002) compared with the reference group (TIS ≤ 0.625 and dIAND < 15 mmHg).
conclusionTIS independently predicts cardiocerebral risk and correlates with dIAND. The combined assessment may refine risk stratification in controlled hypertension, offering a practical approach to identify high-risk patients requiring intensified management.
