Table 2 Calculation of standardised cumulative doses for the three different situations in the trial.

1

In the hospital

With intensity indicator

in J/cm²

CD = CD _h × F

$F=\frac{I_A}{I_h}\times \frac{I_{sr}}{I_{cA}}$

2

In the hospital

Without intensity indicator

in time (seconds)

CD = CTT × I _A × F

$F=\frac{I_{cA}}{I_{cA}}\times \frac{I_{sr}}{I_{cA}}$

3

At home

Without intensity indicator

in time (seconds)

$CD=CTT\times \frac{I_{B1}+I_{B2}}{2}\times F$

$F=\frac{I_{cA}}{I_{cB}}\times \frac{I_{sr}}{I_{cA}}$
