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: There are several known risk factors for ACL injury including knee valgus moment, smaller notch width index (NWI), female sex, increased tibial slope, and meniscal deficiency. Among these, the NWI has typically been determined using either coronal or axial magnetic resonance imaging (MRI) cuts; however, it is unknown whether these measurements differ in each plane. Purpose: To compare axial versus coronal NWI measurements in ACL-injured patients to establish a benchmark for calculation. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Patients ≥14 years of age with a confirmed ACL injury on MRI were included for review. Two orthopaedic resident physicians measured the NWI using both axial and coronal cuts using previously described measurement criteria as well as a modification utilizing the MRI cuts with the widest bicondylar width. The NWI was computed and a Results: A total of 64 patients with ACL injuries were included. Modified axial and coronal NWIs for the cohort were a mean ± SD of 0.27 ± 0.02 and 0.23 ± 0.02, respectively. Modified axial NWIs were greater than coronal NWIs ( Conclusion: NWIs were greater when measured on an axial MRI compared with the coronal plane for both measurement methods. This was because notch widths were measured wider in this plane since intercondylar distances were not statistically different.
