a

Accuracy rating was an 11‐point scale (0–10).

b

Accuracy rating was a 10‐point scale (1–10).

c

The original paper had 38 participants, however due to missing diary data from one participant and missing IES‐R data from another participant, only n = 36 were available for analysis.

d

One participant had missing age/gender data and one participant indicated they prefer not to answer the gender question.

e

Only per‐protocol participants.

f

Three participants had missing diary data, therefore only 84 participants were included in analysis.

g

Had experienced/witnessed a traumatic event.

h

Only per‐protocol participants, n = 30 rated diary accuracy and an additional seven participants had missing data for IES‐R and could not be included in analysis.
