Different types of windows were used to obtain longitudinal data. Each gray box represents a single window, which can vary in duration (length of time) depending on the study. One window with the whole encounter means the study used a single window containing data with a duration of the whole encounter from admittance until discharge. One window before onset signifies data from a window with a duration of time before sepsis, severe sepsis, or septic shock onset. Sliding windows are consecutive windows until before sepsis, severe sepsis, or septic shock onset; this includes non-overlapping and overlapping sliding windows. Non-overlapping sliding windows indicate that data within one window of a fixed duration does not contain data in the next window. In contrast, overlapping sliding windows indicate windows of a fixed duration overlap, and data within one window will be partially in the next window.
