Table 2 P-wave dispersion (ms) and QT dispersion (ms) in CD patients and healthy controls

The measurements of P and QT waves	CD patients (n=60) (mean ± SD)	Control group (n=60) (mean ± SD)	P-value
Pmax	99±7.6	101±8.0	0.051
Pmin	54±6.0	53±5.7	0.221
Pd	46±5.7	44±5.5	0.156
QTc	416±10	398±12	0.000*
QTd	47±4.8	20±6.1	0.000*

Note:

* P<0.000.

Abbreviations: CD, conversion disorder; SD, standard deviation; ms, milliseconds; QTd, QT dispersion; Pmax, the maximum measurement of P wave; Pmin, the minimum measurements of P wave; Pd, Pmax−Pmin; QTc, corrected QT.

Table 3 BAI and BDI scores in CD patients group and healthy group

The measurements of scales	CD patients (n=60) (mean ± SD)	Control group (n=60) (mean ± SD)	P-value
BAI (mean + SD)	25.2±10.8	3.8±3.2	0.001*
BDI (mean + SD)	11.24±6.15	6.58±5.69	0.01**

Notes:

* P<0.001,

** P<0.01. According to BAI and BDI scores administered to patients and controls: BAI scores were 25.2±10.8 and 3.8±3.2 in the patient and control groups, respectively. BAI scores were statistically significantly higher in the patient group (P<0.001). BDI scores were 11.24±6.15 and 6.58±5.69 in the patient and control groups, respectively. BDI scores were also statistically significantly higher in the patient group (P<0.01).

Abbreviations: CD, conversion disorder; BAI, Beck Anxiety Index; BDI, Beck Depression Index; SD, standard deviation.
