Lahoti 2008.

Methods	RCT. Matched pair design
Participants	13 participants with bilateral CTEV requiring soft tissue release Inclusion criteria: bilateral resistant CTEV undergoing soft tissue release Exclusion criteria: none stated PARTICIPANT CHARACTERISTICS Age mean (range) in months: 10 (9 to 12) Baseline severity: 11 idiopathic cases, 2 syndromal cases. Pirani score 5.5 in 6 children and 6 in 7 children FHL and FDL lengthening Age mean: 10 months Sex male (%): 77% Characteristics of feet: 13 feet. 5 right, 8 left Baseline severity: 5.5 average Pirani score FHL and FDL decompression Age mean: 10 months Sex male (%): 77% Characteristics of feet: 13 feet. 8 left, 5 right Baseline severity: 5.5 average Pirani score
Interventions	Lengthening of FHL and FDL versus simple decompression of the same muscles during soft tissue release for resistant CTEV Randomisation of feet (not participants) All participants had bilateral CTEV requiring surgery All feet underwent a complete soft tissue release through the Cinicinnati incision. One side was randomly selected to undergo FHL and FDL lengthening, the other side simple decompression Postoperative management the same in all feet Follow‐up average: 48 months
Outcomes	Harrold and Walker scale Pirani score
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Not stated
Allocation concealment (selection bias)	Unclear risk	Insufficient information
Blinding (performance bias and detection bias) All outcomes	High risk	Surgeon not blinded to intervention. Assessors were blinded. Blinding of participants unlikely to affect outcome
Incomplete outcome data (attrition bias) All outcomes	Low risk	No missing data
Selective reporting (reporting bias)	Unclear risk	Insufficient information on outcome measures
Other bias	Unclear risk	2 syndromic feet were included
