Temporal Profile of Stroke-Associated Pneumonia and Deep Vein Thrombosis after Stroke.
Article in Cerebrovascular diseases extra, 2026. 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
introductionPoststroke complications pose significant challenges in the management of stroke patients and are associated with adverse outcomes. The potential interplay and temporal sequence of stroke-associated pneumonia (SAP) and deep vein thrombosis (DVT) following stroke remain unclear. This study aimed to investigate the association between SAP and DVT and to elucidate temporal sequence of these complications after acute ischemic stroke (AIS), intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH).
methodsWe conducted a study using the in-hospital Medical Complications after Acute Stroke (iMCAS) registry at Beijing Tiantan Hospital from 2014 to 2016. We documented the incidence of SAP and DVT and the time from stroke onset to diagnosis of each complication. A time-dependent Cox regression model was used to evaluate the association between SAP and DVT, and the temporal sequence was compared across AIS, ICH, and SAH.
resultsA total of 1,771 patients were included, comprising 1,129 with AIS, 314 with ICH, and 328 with SAH. The incidence of SAP was higher than that of DVT in AIS (7.6% vs. 1.9%), ICH (18.8% vs. 5.7%), and SAH (16.8% vs. 7.9%). SAP occurrence was significantly associated with subsequent DVT development (HR = 3.65, 95% CI: 2.08-6.40, p < 0.001). This association was also confirmed in AIS and ICH. The median time from stroke onset to SAP was 4 days (IQR: 2-6), and to DVT was 8 days (IQR: 5-12). SAP occurred significantly earlier than DVT in all stroke subtypes.
conclusionSAP was significantly associated with an increased risk of subsequent DVT, with a consistent temporal sequence in which SAP preceded DVT.
