1 · What the graph read from it

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.

2 · The registry

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

The Recurrent Stroke Prevention Clinical Outcome (RESPECT) Study and its pooled analysis showed that intensive blood pressure (BP) lowering reduced recurrent stroke risk by 22% in patients with a history of stroke. Here, we report the effect of intensive BP lowering on the risk of recurrent stroke subtypes in patients with a history of ischemic stroke. RESPECT was a randomized clinical trial among 1280 people with a history of cerebral infarction or intracerebral hemorrhage. Participants were assigned to the intensive blood pressure control group (blood pressure < 120/80 mmHg) or standard blood pressure control group (blood pressure < 140/90 mmHg). In this post hoc analysis, we analyzed 1074 patients with a history of cerebral infarction. The mean BP at baseline was 140.7/81.4 mmHg. Throughout the follow-up period, the mean BP was 133.4/77.5 (95% CI, 132.7-134.1/76.9-78.2) mmHg in the standard group and 126.7/74.1 (95% CI, 126.0-127.4/73.5-74.8) mmHg in the intensive group. During a mean follow-up of 3.9 years, 78 first recurrent strokes occurred. Intensive treatment tended to reduce overall annual stroke recurrence (1.74% in intensive vs. 2.17% in standard; P = 0.351 by log-rank test) and did not change the risk of ischemic stroke (1.74% vs. 1.75%, P = 0.999) but markedly reduced the risk of hemorrhagic stroke (0.00% vs. 0.39%, P = 0.005). Beneficial effects of intensive BP control were observed for the risk of hemorrhagic stroke in patients with a history of ischemic stroke. The findings of this study indicate the benefit of intensive BP control for patients with a history of ischemic stroke at high risk of hemorrhagic stroke.
