Journal Article
Duff, C. J., Solis-Trapala, I., Driskell, O. J., Holland, D., Wright, H., Waldron, J. L., …Fryer, A. A. (2018).

Introduction:
We previously showed, in patients with diabetes, that >50% of monitoring tests for glycated hemoglobin (HbA1c) are outside recommended intervals and that this is linked to diabetes control. Here, we examined the impact of tests/year on...

A simplified approach to estimating the distribution of occasionally-consumed dietary components, applied to alcohol intake (2016)
Journal Article
Solis-Trapala. (2016). A simplified approach to estimating the distribution of occasionally-consumed dietary components, applied to alcohol intake. BMC medical research methodology, 78 - 88 (11). https://doi.org/10.1186/s12874-016-0178-3

Background
Within-person variation in dietary records can lead to biased estimates of the distribution of food intake. Quantile estimation is especially relevant in the case of skewed distributions and in the estimation of under- or over-consumption...

Background
A growing number of studies report cognitive impairment after chemotherapy; indeed the phenomenon of chemo-fog is now almost universally accepted. We are concerned however that there is little if any consistency in the way in which patien...
