CAD/CAM nitinol bonded retainer versus a chairside rectangular-chain bonded retainer: A multicentre randomised controlled trial.
Trial report in Journal of orthodontics, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 2 of them syntheses that pooled 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.
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
backgroundBonded retainers are widely used to maintain the positions of anterior teeth after orthodontic treatment. Various types of bonded retainer exist however, there is a lack of evidence to indicate which type is superior.
aimTo compare upper and lower CAD/CAM nitinol bonded retainers (Memotain TRIAL
designMulti-centre, two-arm, parallel-group, randomised controlled clinical trial with 1:1 allocation.
settingThree trial centres: University Teaching Hospital; District General Hospital; and Specialist Orthodontic Practice. All treatment was provided free as part of a state-funded healthcare system. MATERIALS AND
methodsA total of 68 patients were randomly allocated to receive either upper and lower Memotain
resultsThe trial was terminated due to the high number of failures (50%) of the upper Memotain® retainers within six months. Memotain LIMITATIONS: Early termination of the trial means that the a priori sample size was not reached, so outcomes should be interpreted with caution.
conclusionThe trial was terminated early due to the high failure rate of upper Memotain
