Table 5. Comparison of area95 (Unit: centimeter)

Group	Pre	Post	Difference value	Time (P value)	Group×time (P value)	Group (P value)	P value
EG	4.87±3.37	4.47±2.92	-0.40±3.52	0.06	0.15	0.41	0.55
CG	7.21±5.86	4.56±3.77	-2.65±4.03	-	-	-	0.03*

EG: experimental group (with small props).
CG: control group (without small props).
Pre: before intervention (mean ± standard deviation).
Post: after intervention (mean ± standard deviation).
Difference value: change between pre and post.
Time (P value): P-value for within-group change over time.
Group×time (P value): P-value for interaction between group and time.
Group (P value): P-value comparing groups (post–pre difference).
P value (Bonferroni adjusted, α = 0.025): Bonferroni-corrected p-value for multiple comparisons.
P < 0.05.
