Subchondral insufficiency fracture of the knee: unicompartmental correlation to meniscal pathology and degree of chondrosis by MRI.
Article in Skeletal radiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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.
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
objectiveTo assess the relationship between low- and high-grade subchondral insufficiency fracture of the knee (SIFK) and meniscal tear/type/location, severity of meniscal extrusion, grade of chondrosis, and extent of surrounding edema-like marrow signal intensity. MATERIALS AND
methodsOur retrospective study included 219 patients with knee pain and SIFK seen on MRI. SIFK lesions were categorized from grade 1 to 4 with a low grade (1 and 2) vs high grade (3 and 4) distinction. Associations between SIFK grade, location, lesion dimensions, edema-like marrow signal intensity, incidence of meniscal tears/type/location, and chondrosis (grade 0 to grade 4), as well as patients' age and weight, were assessed.
resultsOur analysis consisted of 115 males and 104 females with 17% of the patients showing grade 1 SIFK, 59% grade 2, 16% grade 3, and 8% grade 4. No chondrosis or low-grade chondrosis was mostly present in patients with low-grade SIFK (68.9%), whereas high-grade chondrosis was mostly present in patients with high-grade SIFK lesions (65.4%) (p < 0.01). Further sub-analysis demonstrated that high-grade SIFK was associated with high-grade chondrosis in the same compartment (p < 0.01) but not in the adjacent compartment. There was a significant difference in the extent of edema-like marrow signal intensity between the two groups, with high-grade SIFK more frequently demonstrating severe edema-like marrow signal intensity compared to low-grade SIFK (p < 0.01).
conclusionHigh-grade SIFK lesions are associated with unicompartmental high-grade chondrosis.
