Number of knots tied with each method, and proportion of knots tied with each method that slipped on testing, mean length of slippage MM, and proportional increase in amount of suture material held within knot post slippage, for each method and 95% CI
Method of formation of square reef knot | No of knots tied | No and proportion (%) of knots that slipped on testing | Mean length of slippage, mm and proportional degree of slippage, (%), recorded for knot method | 95% lower CI, mm (%) | 95% upper CI, mm (%) | Median length of slippage mm |
Flat reef knot | 120 | 24 (20) | 1.2 (6.3) | 0.5 (2.2) | 2.0 (10.4) | 0.0 |
No hand crossing knot | 120 | 120 (100) | 18.5 (113.0) | 15.5 (94.3) | 21.5 (131.0) | 11.9 |
Knot tied under tension | 120 | 120 (100) | 50.6 (312.0) | 45.9 (280.0) | 55.4 (344.0) | 51.5 |
