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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Anterior cruciate ligament reconstruction (ACLR) hamstring (HS) autograft diameter <8 mm is associated with an increased re-rupture rate. Efforts have been made to increase graft diameter by using more than 4 strands.The purpose of this study was to report graft sizes and outcomes using a novel modified 5- or 6-strand HS ACLR. Methods: A retrospective study was conducted with patients who underwent primary ACLR through a 5-year period. Patients were divided into 2 groups based on graft choice: 5- or 6-strand HS versus the remainder of the cohort (BTB, QT, or 4-strand HS). Results: There were 70 patients in group 5/6, and 48 patients in group CG (20 4-strand HS and 28 BTB/QT). The average follow-up was 47.7 months. Re-rupture rate in Group 5/6 was 2.9 % (2/70) compared to 8.3 % (4/48) (p = .2225) in group CG. The subsequent surgery rate for group 5/6 was 5.7 %, versus 12.5 % for group CG (p = .3128). Conclusion: 5 or 6 Strand ACLR provides graft sizes >8 mm in 98.6 % of cases, good clinical outcomes including low re-rupture and subsequent surgery rates, and good patient-reported outcomes. At an average follow-up of 4 years, 5 or 6 Strand ACLR revealed trends of lower re-rupture rates, lower subsequent surgery rates, and lower cyclops lesion rates compared to BTB/Quad and 4-strand hamstring grafts; however, these results were not statistically significant.
