Ultrasound Measurements of the ECRB Tendon Shows Remarkable Variations in Patients with Lateral Epicondylitis.
Article in The archives of bone and joint surgery, 2020. 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
backgroundLateral epicondylitis (LE) most commonly affects the Extensor Carpi Radialis Brevis (ECRB) tendon and patients are generally treated with injection therapy. For optimal positioning of the injection, as well as an estimation of the surface area and content of the ECRB tendon to determine the volume of the injectable needed, it is important to know the exact location of the ECRB in relation to the skin as well as the variation in tendon length and location. The aim of this study was to determine the variation in location and size of the ECRB tendon in patients with LE.
methodsAn observational sonographic evaluation of the ECRB tendon was performed in 40 patients with LE. The length of the ECRB tendon, distance from the cutis to the center of the ECRB tendon, the length of the osteotendinous junction at the epicondyle and the distance from cutis to middle of the osteotendinous junction were measured.
resultsThe average tendon length was 1.68cm (range 1.27-1.98; SD 0.177). Compared to women, the ECRB tendon of men was on average 0.12cm longer. Overall, the average distance from cutis to the center of the ECRB was 0.75cm (range 0.50-1.46cm; SD 0.210), the average length of the junction was 0.55cm (range 0.35-0.87; SD 0.130), and the distance from cutis to middle of the osteotendinous junction was 0.73cm (range 0.40-1.25cm; SD 0.210).
conclusionThe size and depth of the ECRB tendon in patients with LE is largely variable. While there are no studies yet suggesting sono-guided injection to be superior to that of blind injection, the anatomic variability of this study suggests that the accuracy of injection therapy for LE might be compromised when based solely on bony landmarks and therefore not fully reliable. As a result, there is value in further studies exploring the accuracy of the ultrasound guided injection techniques.
