Patient or population: anterior cruciate ligament reconstruction
Setting:
Intervention: Quadriceps tendon autograft
Comparison: hamstring tendon autograft
Outcomes	Anticipated absolute effects ^* (95% CI)		Relative effect (95% CI)	Nº of participants (studies)	Certainty of the evidence (GRADE)	Comments
Outcomes	Risk with hamstring tendon autograft	Risk with Quadriceps tendon autograft	Relative effect (95% CI)	Nº of participants (studies)	Certainty of the evidence (GRADE)	Comments
Function follow-up: mean 3 years	The mean function was 89.43	mean 85.59 higher (0 to 0)	-	436 (6 RCTs)	⨁⨁⨁◯ MODERATE	There were no differences in knee function between quadriceps tendon autograft and hamstring autograft (p = 0.08).
Pain follow-up: range 48 Years to 24 months	383 per 1.000	341 per 1.000 (218 to 533)	RR 0.89 (0.57 to 1.39)	254 (4 RCTs)	⨁⨁⨁◯ MODERATE	There were no differences in pain between the groups analyzed after the intervention (p = 0.60).
Return to sport follow-up: median 2 years	The mean return to sport was 82.1	mean 95.2 higher (0 to 0)	-	51 (1 RCT)	⨁⨁⨁⨁ HIGH	There were no significant differences (p < 0.131) in time to return to sport between groups.
Complications - Re-rupture follow-up: range 12 months to 3 years	11 per 1.000	0 per 1.000 (0 to 0)	no estimates	371 (5 observational studies)	⨁⨁◯◯ LOW	There were no differences in rupture following quadriceps tendon autograft and hamstring autograft (p = 0.38).
*The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).

CI: Confidence interval; RR: Risk ratio
GRADE Working Group grades of evidence
High certainty: We are very confident that the true effect lies close to that of the estimate of the effect
Moderate certainty: We are moderately confident in the estimated effect: The true effect is likely to be close to the estimated effect, but there is a possibility that it is substantially different
Low certainty: Our confidence in the estimated effect is limited: The true effect may be substantially different from the estimated effect
Very low certainty: We have very little confidence in the estimated effect: The true effect is likely to be substantially different from the estimated effect
