Let's take a look at this study; again, a complex study with many variables and no clear indication as to what scale was used for what etc. Start with the methods section: you see that they used several scales, we will use only the KAMA scale for this paper. The length of follow up was for a year; this scale was based on presenting a vignette to the carers and then seeking their responses. The authors did not report the range of scores, so we type "NA" in the relevant boxes. The type of outcome is "continuous".
This is a continuous outcome as the scores of the KAMA can be plotted over a scale. You will see if you read the study that the carers' scores increased and/or decreased. When you faced with this kind of metrics in a paper think of "continuous" measures for outcomes. Hence we click on "continuous" as outcome type, and we click "single study" as our study. Then save and proceed to fill in the particular outcome details.
