Figure 1
From: Risk score to predict gastrointestinal bleeding after acute ischemic stroke
The figure showed the proportion of in-hospital GIB after AIS according to the AIS-GIB score in the derivation (blue bar), internal (red bar) and external (yellow bar) validation cohort. The risk of in-hospital GIB after AIS increased steadily with higher AIS-GIB score. Meanwhile, the predicted (green dot line) and observed risk of in-hospital GIB after AIS were in close agreement in the derivation, internal and external validation cohort.
