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
backgroundTricortical pedicle screw (TCPS) is a novel method for thoracic fixation to prevent proximal junctional kyphosis in scoliosis correction surgery. However, there is limited reports on the radiographic parameters of TCPS trajectories. Through computational simulation of TCPS placement in thoracic vertebrae utilizing three-dimensional digital modeling, this study sought to elucidate the ideal radiographic trajectory parameters and compare them with the real data from clinical practice, evaluating the technique's feasibility and safety, thereby providing essential radiological reference data for surgical strategy optimization.
methodsA total of 207 ASD patients were retrospectively reviewed (Group C
resultsFor the ideal trajectory parameters simulated in Group C1 and Group C2 patients, the parameters were comparable between the two groups. When stratified by sex, males exhibited significantly longer trajectory lengths at each vertebral level compared to females (p < 0.05). For both males and females, the greatest SA was observed at T
conclusionsOur comprehensive radiological assessment of ideal and actual TCPS screw trajectories elucidated gender-specific variations and demonstrated the clinical feasibility of achieving ideal trajectory in female patients. These findings provide valuable information on TCPS insertion protocols in clinical practice.
