Article in European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2017. 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
purposeTo evaluate the influence of the position of the arms on the location of the body's gravity line. PREVIOUS DATA: The sagittal balance of the pelvi-spinal unit is organized so that the gravity line is localized in a way that limits the mechanical loads and the muscle efforts. This position of the gravity line was analyzed in vivo, in standing position, the arms dangling, by the barycentremeter, a gamma rays scanner. Then, several teams had the same purpose but using a force platform combined with radiographies. Their results differed significantly among themselves and with the data of the barycentremetry. However, in these studies, the positions of the arms varied noticeably, either slightly bent forwards on a support, or the fingers on the clavicles or on the cheeks.
methodsWe estimated, for each varied posture of the arms, the sagittal coordinates of the masses of the upper limbs and their influence on the anatomical position of the gravity line of the whole body.
resultsUsing a simple equation and the data of the barycentremeter, we observed that the variations in the location of the gravity line were proportionally connected to the changes of the sagittal position of the mass of the upper limbs induced by the various positions of the arms.
conclusionsWe conclude in a validation of the data of the barycentremeter, as well as of the data obtained by the force platforms as long as the artifact of the position of the arms is taken into account.
