Measurement of midshaft clavicle vertical displacement is not influenced by radiographic projection.
Article in JSES international, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundMeasured shortening of midshaft clavicle fracture fragments is known to be influenced by multiple factors. The influence of radiographic projection on vertical displacement is unclear. The aims of this study were (1) to quantify the difference in measurements of vertical displacement in an absolute, relative, and categorical manner between 5 different projections; (2) to quantify the differences in interobserver and intraobserver agreement using a standardized method for measuring vertical displacement; and (3) to assess the association between categorical and continuous descriptions of vertical displacement. MATERIALS AND
methodsA clinical measurement study was conducted on 31 sets of digitally reconstructed radiographs in 5 different projections (15° and 30° caudocranial, anteroposterior, and 15° and 30° craniocaudal views). Categorical data on vertical displacement in quartiles from 0%-200% were obtained followed by measurements using a standardized method by 3 observers at 2 points in time. Interobserver and intraobserver agreement for each of the 5 views was calculated.
resultsThe absolute and relative vertical displacement showed no statistically significant difference between any of the caudocranial, anteroposterior, and craniocaudal views. Intraclass correlation coefficients for intraobserver and interobserver agreement were good to excellent. The correlation between categorical outcomes and both absolute and relative vertical displacement was very strong.
conclusionUnlike shortening, absolute and relative vertical displacement of the midshaft clavicle fracture is not significantly influenced by radiographic projection. Standardized measurements of vertical displacement may not be necessary for clinical use because the correlation between categorical and continuous measurements was found to be very strong.
