Comparison of single versus double coracoclavicular loop stabilization technique for the management of unstable distal clavicular fractures: a randomized controlled trial.
Trial report in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 2024. 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
purposeThe coracoclavicular (CC) loop stabilization technique is proposed for unstable distal clavicular fractures. This study aims to compare single and double CC loop stabilizations and evaluate differences in functional and radiographic outcomes between them.
methodsWe conducted a prospective randomized controlled trial involving 46 patients who sustained unstable distal clavicular fractures between April 2017 and 2019. The participants were randomly assigned to one of two groups: the single CC loop stabilization group (n = 23) or the double CC loop stabilization group (n = 23). We assessed their Constant score, American Shoulder and Elbow Surgeons score (ASES), and pain level. Additionally, we recorded data on time to union, CC distance, and any complications.
resultsThe single CC loop group demonstrated a shorter operative time and significantly higher Constant score than the double CC loop group at 1 month (77.32 ± 5.65 vs. 71.91 ± 8.33; p = 0.016) and 3 months (86.17 ± 4.05 vs. 81.13 ± 6.34; p = 0.009) postoperatively. However, there was no differences in the ASES score, time to union or CC distance restoration between two groups. Implant irritation was observed in the double CC loop group (26.1%), but there were no cases requiring revision surgery.
conclusionsBoth single and double CC loop stabilization demonstrated favorable outcomes, including a high union rate and minimal complications. Single CC loop stabilization showed slightly better early functional outcomes, reduced implant-related irritation, and shorter operative times.
