[Effects and sustainability of knee school : 2-year results of a secondary prevention program for gonarthrosis].
Article in Der Orthopade, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCraftsmen and workers in the construction industry are at an increased risk of developing gonarthrosis due to their work-related burdens. In order to maintain the ability to work, occupational co-operative measures for secondary prevention can be carried out (BG Bau/Kniekolleg). The aim was to evaluate the efficacy after 2 years, depending on the degree of exercise adherence. MATERIAL AND
methodsIn a repeated measurement design (T1 before, T2 after knee school, T3 after 1 year, T4 after 2 years), 140 construction patients were assessed for their dynamic muscular strength (knee extension, 60°/s,); their quality of life (SF-36) and characteristics for gonarthrosis (WOMAC) were evaluated using analyses of variances, whereby one group trained after the knee training in the gym with instruction (Gr. 1 n = 63), one group completed a home-training program (Gr. 2 n = 38), and one group completed exercises outside of knee school (Gr.3 n = 39).
resultsFor all parameters, significant acute efficacy and 2‑year sustainability effects were observed (p ≤ 0.05, d: 0.2-0.8). There was no interaction with adherence during training after knee school (p > 0.05).
conclusionKnee school has proved to be effective in the long term, leading to a critical questioning of future research, why there are no differences between guided, reduced or even missing long-term maintenance training.
