Tibial tunnel widening following anterior cruciate ligament reconstruction: A retrospective seven-year study evaluating the effects of initial graft tensioning and graft selection.
Trial report in The Knee, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00434837 (Effects of Initial Graft Tension on Anterior Cruciate Ligament Reconstruction), which is not on this map. Cited by 14 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
purposeTo investigate tibial tunnel widening in ACL reconstruction patients over seven years to establish the effects of initial graft tension on tibial widening and clinical outcomes when using both patellar tendon (BTB) and hamstring tendon (HS) grafts.
methodsNinety patients, who were reconstructed with BTB or HS autografts, were randomized using one of two initial graft tension protocols; 1) tensioned to restore normal anteroposterior laxity ("low-tension"; n = 46) and 2) tensioned to over-constrain anteroposterior (AP) laxity by two millimeters ("high-tension"; n = 44). Seventy patients had post-surgical data with 45 available for review at seven years. Tunnel widening was assessed via radiographs at one-, three-, and seven-year follow-up. Patient-reported outcomes were compared.
resultsThe mean ± 95% confidence intervals of the initial diameters for the BTB autografts were 10.3 ± 0.5 mm (Low-tension) and 10.2 ± 0.6 mm (High-tension) with final diameters of 10.8 ± 0.6 mm (Low-tension) and 9.9 ± 0.6 mm (High-tension). The initial diameters for HS autografts were 8.1 ± 0.9 mm (Low-tension) and 8.4 ± 0.7 mm (High-tension) with final diameters of 11.5 ± 1.1 mm (Low-tension) and 11.1 ± 0.9 mm (High-tension). For subjects with HS autografts, mean tunnel diameters significantly changed over time (p < .001); no significant changes were observed in BTB autografts (p = .29). Change in diameter of the HS autograft group remained significantly greater than the BTB group at all time points for both tension groups (p < .05). No differences in patient-reported outcomes were found between tension groups or graft types.
conclusionsPatients who underwent ACL-R with HS autograft exhibited tibial tunnel widening over seven years. Patients with BTB autografts did not experience widening, regardless of initial graft tension. Patient-reported outcomes were equivalent.
