Photograph of face-mask in series with pneumotachograph and nebuliser used for nebulisation of tartaric acid and measurement of reflex cough flow. - Figure S2 -
Figure S2A shows the regression line (with 95% confidence intervals) drawn on a scatter diagram showing the relationship between reflex and voluntary cough flow rate for 17 stroke patients and 18 controls. This diagram includes those participants who did not produce voluntary or reflex coughs but does not include the 3 participants unable to tolerate tartaric acid administration. Voluntary cough flow rate increases by 1.2 l/min per 1 l/min increase in reflex cough flow rate, 95% CI 0.9 to 1.4 l/min, P <_0.001 adjusted="adjusted" r2="0.736." figure="figure" s2b="s2b" shows="shows" patients="patients" and="and" controls="controls" marked="marked" using="using" different="different" symbols="symbols" see="see" key.--="key.--" end="end" desc="desc" dc1="dc1" _2="_2" _--="_--"> - Tables S2 and S3, figures S3 and S4 -

Table S3 Results of an unpaired t-test to compare number of reflex coughs elicited at maximum strength tartaric acid for stroke and control groups
Figure S3 Scatter dot plot to show the number of coughs elicited by the maximum strength of tartaric acid administered to each participant. Horizontal lines show mean and the 95% confidence interval for the mean
Figure S4 Raw data acquired during reflex cough testing in a control subject (top panel, Figure S3A) and a stroke patient (bottom panel, Figure S3B) - Table S1 -
Results of multivariate linear regression analysis performed to predict voluntary cough flow rate from NIHSS score (stroke severity score), height and FEV1 /FVC ratio.
