Fig. 1

Suicidal ideation subgroups. The line plot depicts the suicidal ideation (SI) trajectories by estimated class: (1) “High SI, moderate variability” subgroup, (2) “Lowest SI, lowest variability” subgroup, (3) “Low SI, moderate variability” subgroup, and (4) “Highest SI, highest variability” subgroup. A LOESS line is fitted to the trajectories of each subgroup to depict the average trend. The mean of the overall sample is zero, and this transformation was applied prior to the analysis. If the LOESS line dips below zero, it indicates that the fitted SI for that subgroup has fallen below the mean of the overall sample. On the x-axis, measurement occasions are depicted with zero, representing the day post-discharge from acute psychiatry and the start of EMA, and 140 is the maximum of possible data points (5 prompts per day for 28 days)
