Descriptive statistics for PCS scores.

PCS score	Finger pressure	Stress relief	Elastomeric wafer	Chi square	P value
Rumination	5a	5a	8b	18.20	≤0.001∗ (s)
Magnification	4a	3b	4a	10.40	0.02∗ (s)
Helplessness	4b	5a	6a	6.63	0.04∗ (s)
Total	14	12	18	19.39	≤0.001∗ (s)

^∗(P < 0.05) and statistically significant. Post hoc test was conducted to pinpoint a difference within the groups. Different alphabets express that there is a statistically significant difference: EW has a high score in the rumination group compared to FP and SR. SR has the lowest score compared to FP and EW in terms of magnification. FP has the lowest score compared to SR and EW in terms of helplessness.
