A Multiplanar Reformatting Technique to Correct for Scanner Misalignment During Computed Tomography Measurement of Tibial Tuberosity-Trochlear Groove Distance.

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
The tibial tuberosity-trochlear groove distance (TT-TG) is a commonly used measurement that impacts clinical decision making for patellofemoral instability. When measured using 2-dimensional axial slices from imaging modalities like computed tomography (CT) scans, it has been shown to be prone to error depending on patient alignment with the scanner's longitudinal axis. In this technique article, we describe a method using multiplanar reformatting on 2-dimensional CT scans to create an altered coordinate system to measure TT-TG measurements more accurately and efficiently. This method can drastically impact the accuracy and reproducibility of TT-TG measurements for misaligned scans and can help ensure that patients are treated appropriately for their individual level of dysplasia.
