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

objectiveLamina-implantation is gradually becoming the main surgical method for the treatment of intraspinal tumors. Traditional titanium (Ti) internal fixation not only produces artifacts, which affects the observation of tumors and dural sac closure, but also faces the problem of secondary surgical removal. In this study, absorbable material were used in lamina replantation for the first time and was evaluated for its efficacy and safety.

methodsWe retrospectively enrolled patients who underwent short-segment lamina replantation for intraspinal tumors in our center from February 2020 to November 2022. After condition matching of the number of fixation segment and fixation position, the baseline information, complications, neurological function, quality of life, spinal mobility and bone healing rate of the absorbable group and the Ti group were compared. Fisher exact, Chi-square, or rank sum test were used for categorical variables, and t-test was used for continuous variables to distinguish differences between groups.

resultsCerebrospinal fluid leak was the most common complication, with no difference between the two groups (12.9% vs. 19.4%, p = 0.366). The bone healing rates of the two groups at 3 months after surgery were 77.4% and 87.1%, respectively, and there was no significant difference (p = 0.508). At 1 year after surgery, the resorbable group showedlower levels of anxiety/depression (1.20 ± 0.41 vs. 1.61 ± 0.61, p = 0.050), however, it did not affect the overall quality of life of the patients at 1 year.

conclusionBoth titanium and absorbable internal fixation have shown good clinical results in the treatment of intraspinal tumors by laminareplantation. Regardless of cost, absorbable screws and plates are also suitable options for patients undergoing lamina replantation, because it has no stress shielding effect and does not require secondary removal. In addition, there are no artifacts in the image, which is more conducive to observing the recurrence of the tumor and the closure of the dural sac.
