1 · What the graph read from it

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.

2 · The registry

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 identify independent predictors of postoperative axial symptoms (AS) after cervical laminoplasty (CLP) and evaluate the predictive value of preoperative cervical range of motion.

methodsWe retrospectively reviewed 191 patients with cervical spondylotic myelopathy who underwent unilateral open-door CLP between January 2019 and January 2024. Patients were classified into AS (n=73) and no AS (n=118) groups. Demographic, surgical, radiographic, and clinical variables were compared. Binary logistic regression identified independent predictors, and receiver operating characteristic analysis assessed predictive performance.

resultsCompared with the no-AS group, the AS group had higher BMI (26.5±3.7 vs. 25.4±3.3 kg/m

conclusionReduced preoperative extension ROM and non-preservation of C7 independently predicted AS after CLP. These parameters may improve AS risk stratification.
