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
purposeThe purpose of this study was to reveal the correlation between the type of lesion and the depth of osteoarthritic (OA) changes in the patello-femoral (PF) joint and its bony morphological characteristics using computed tomography (CT) data.
methodsEighty-seven cadaveric knees were included in this study with median age of 83 years (62-97). OA depth evaluation was performed following Outerbridge's classification. Patella OA lesions were classified macroscopically using Han's method: type (1) no or minimal lesion, type (2) medial facet lesion without involvement of the ridge, type (3) lateral facet lesion without involvement of the ridge, type (4) lesion involving the ridge only, type (5) medial facet lesion with involvement of the ridge, type (6) lateral facet lesion with involvement of the ridge, and type (7) global lesion. Femoral-side OA lesions in the PF joint were classified using a modified Chang's method. Type (1) no or minimal lesion, type (2) medial facet lesion, type (3) centre of patella groove lesion, type (4) lateral facet lesion, and type (5) global lesion. Whole-body CTs of all cadavers were taken before knee dissection. Using the CT data, patella morphology was evaluated following Wiberg's classification. Femoral sulcus angle (SA), sulcus depth (SD), and sulcus width (SW) were also measured using CT data.
resultsThe measured SA, SD, and SW were 144.8° ± 7.2°, 7.0 ± 1.6 mm and 3.4 ± 0.3 mm, respectively. When patella OA depth was divided into grades 1-2 (n = 30) and grades 3-4 (n = 57), the SD of grade 1-2 knees was 6.5 ± 1.3 mm, and the SD of grade 3-4 knees was 7.3 ± 1.6 mm, constituting a significant difference (p = 0.01). No significant difference in either SA or SW was observed between the two groups. Patella OA lesion, femoral-side OA lesion, and depth were not affected by SA, SD, or SW. Wiberg's classification also showed no significant correlation with PF-OA.
conclusionDeep SD was significantly correlated with the incidence of severe patella OA. Wiberg's classification, SA, and SW were not correlated with PF-OA. For clinical relevance, there is a risk of PF-OA progression in patients with deep SD, and treatment should be applied accordingly.
