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
Background: Accurate cup placement is performed for achieving satisfactory outcomes after total hip arthroplasty. Portable hip navigation systems are novel intraoperative tools for accurate cup placement. Several factors have been reported to affect their accuracy, including the flip technique, in which the pelvic reference plane is registered in the supine position and the patient is subsequently repositioned to the lateral decubitus position for surgery. The effectiveness of the flip technique remains a subject of debate. Therefore, this study assessed and compared the accuracy of cup position measurements using an inertial portable hip navigation system in the lateral decubitus position. Methods: Measurement accuracy was assessed in 78 hips. The accuracy of the system was compared with and without the flip technique, employing an identical method for registering the pelvic reference plane. Cup angles displayed on the system during surgery were compared with those measured postoperatively. Results: Measurement errors with and without the flip technique were 3.7° ± 2.8° and 2.8° ± 2.6° for cup abduction ( Conclusions: This system provided reliable intraoperative measurements of cup positions, irrespective of the use of the flip technique. However, cup abduction measurements were more accurate without the flip technique, while cup anteversion measurements were more accurate with the flip technique.
