Table 4 Summary of findings

Outcomes	Intervention values	Control values	Number of patients	Quality of evidence (GRADE)	Comments
PDI	0.335/mo	1.355/mo	121	Very low	Only studies with cross-over design were analyzed
	MD: -1.12
	95%CI: -1.99 to -0.25
	P = 0.012
TNRD	n/a	n/a	165	Very low	Different length of follow up results in high risk of bias
	MD: -1.17
	95%CI: -0.24 to 0.05
	P = 0.057
DS	n/a	n/a	178	Very low	Different scoring scales were used and different lengths of follow up result in high risk of bias
	SMD: 0.35
	95%CI: -0.38 to 1.08
	P = 0.351

PDI: Periodic dilation index; TNRD: Total number of repeat dilations; DS: Dysphagia score; MD: Mean difference; SMD: Standardized mean difference.
