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

objectiveTo explore whether magnetic resonance imaging (MRI) features suggestive of knee osteoarthritis (OA) are associated with presence of knee pain in possible early-stage OA development.

methodsWe included 294 participants from the Osteoarthritis Initiative (mean ± SD age 50 ± 3 years; 50% women) with baseline Kellgren/Lawrence grade of 0 in both knees, all of whom had received knee MRIs at 4 different time points over 6 years (baseline, 24, 48, and 72 months). Using a linear mixed model (knees matched within individuals), we studied whether MRI features (meniscal body extrusion [in mm], cartilage area loss [score 0-39], cartilage full thickness loss [range 0-16], osteophytes [range 0-29], meniscal integrity [range 0-10], bone marrow lesions [BMLs] including bone marrow cysts [range 0-20], Hoffa- or effusion-synovitis [absent/present], and popliteal cysts [absent/present]) were associated with knee-specific pain as reported on the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire using a 0-100 scale (worst to best).

resultsThe differences in KOOS knee pain score for a knee with a 1 unit higher score on MRI were the following: meniscal extrusion -1.52 (95% confidence interval [95% CI] -2.35, -0.69); cartilage area loss -0.23 (95% CI -0.48, 0.02); cartilage full thickness loss -1.04 (95% CI -1.58, -0.50); osteophytes -0.32 (95% CI -0.61, -0.03); meniscal integrity -0.28 (95% CI -0.58, 0.02); BMLs including potential cysts -0.19 (95% CI -0.55, 0.16); synovitis 0.23 (95% CI -1.14, 1.60); and popliteal cysts 0.86 (95% CI -0.56, 2.29).

conclusionMeniscal extrusion, full thickness cartilage loss, and osteophytes are associated with having more knee pain. Although these features may be relevant targets for future trials, the clinical relevance of our findings is unclear because no feature was associated with a clinically important difference in knee pain.
