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

purposeThe aim of this study was to identify associated risk factors of distal adding-on phenomenon in Lenke 1A/B and 2A/B adolescent idiopathic scoliosis (AIS) patients and establish the corresponding prediction model.

methodsThe clinical data of 119 Lenke 1A/B and 2A/B AIS patients were retrospectively analyzed. Preoperative, first erect (FE) radiographic parameters and radiographic parameters at the last follow-up were measured. Patients were divided into the adding-on group and the no adding-on group according to whether the adding-on phenomenon was observed at the last follow-up. Univariate analysis and multivariate logistic regression analysis were used to establish the corresponding prediction model.

resultsAdding-on affected 39 (32.8%) patients at the last follow-up. Risser sign and 19 radiographic parameters showed significant differences between the two groups by univariate analysis. Stepwise logistic regression analysis found that the Risser sign and so on five predictor variable, and the nomogram was drawn. The calibration curve showed that the model fitted well. The area under the receiver operating characteristic (ROC) curve is 0.949. And the decision curve analysis curve model within the threshold range for interventions to improve clinical outcomes. There was no significant difference in SRS-22 scores between the two groups.

conclusionsThis study established a prediction model with adding-on in Lenke 1A/B and 2A/B AIS patients. The nomogram contains five predictive variables, which can effectively predict the probability of adding-on phenomenon during follow-up, and may have greater clinical value for the treatment and prevention of adding-on phenomenon.
