1 · What the graph read from it

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.

2 · The registry

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

backgroundCurrent knowledge on the microvascular anatomy of adult human menisci is based on cadaveric studies. However, considerable interindividual variation in meniscal microvascularization has been reported in recent studies with small sample sizes. PURPOSE: To assess the association between patient characteristics and the depth of microvascularization of the meniscus. STUDY

designDescriptive laboratory study.

methodsMenisci from 174 patients who received total knee replacement between March 2021 and December 2023 were collected. A total of 174 lateral and 102 medial menisci were included. Three sections were made from each meniscus: the anterior horn, midbody, and posterior horn. Immunohistochemical staining (CD-31) was used to visualize the microvasculature. The 4 primary outcome measures were the correlation between the depth of microvascular penetration into the lateral meniscus (0%-100%) and (1) age, (2) smoking, (3) degree of osteoarthritis, and (4) history of cardiovascular disease. To account for repeated measurements within each patient, a linear mixed-effects model was estimated to study the association between microvascularization and the patient's characteristics previously introduced.

resultsThe depth of vascular penetration ranged from 0% to 78% into the lateral menisci and from 0% to 67% into the medial menisci. No significant correlations were found between age, smoking, degree of osteoarthritis, or history of cardiovascular disease and the degree of vascular penetration into the lateral meniscus. The linear mixed-effects model analysis, adjusted for location within the meniscus (anterior horn, midbody, or posterior horn) and meniscal side (lateral or medial), showed no significant associations between the same patient characteristics and meniscal microvascularization.

conclusionThe degree of microvascular penetration into the meniscus has a wide range among adults >50 years. However, the depth of microvascularization was not associated with age, smoking, degree of osteoarthritis, or history of cardiovascular disease. CLINICAL RELEVANCE: Because no associations were found between depth of microvascular penetration into the meniscus and patient characteristics, the latter cannot be used to estimate the vascular status of a meniscal tear in clinical practice.
