Magnetic resonance imaging of patellofemoral osteoarthritis: intertester reliability and associations with knee pain and function.
Article in Clinical rheumatology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesWe examined the intertester reliability of patellofemoral compartment (PFC) osteoarthritis (OA) severity using magnetic resonance images (MRI) and a modified Kellgren and Lawrence (K&L) system. Second, we determined if these grades were associated with clinical tests of PFC involvement or self-reported pain/difficulty with stair climbing. Third, we assessed the association between PFC OA severity and knee pain or disability, after accounting for potential confounders including tibiofemoral OA severity.
methodWe examined the 9-year Osteoarthritis Initiative data from 114 subjects in the year prior to undergoing knee arthroplasty. The weighted kappa (κ
resultsReliability was substantial (κ
conclusionsMRI-based measures of PFC OA were highly reliable indicating that musculoskeletal radiologists can reliably grade the PFCs of subjects using MRI. The extent of PFC OA is not associated with either clinical tests of PFC involvement or activities associated with PFC pain in persons with moderate to severe symptomatic tibiofemoral and PFC OA.
