Expression and significance of telomerase in the nucleus pulposus tissues of degenerative lumbar discs.

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
The pathogenesis of lumbar disc degeneration is extremely complex, and the expression and role of telomerase in degenerative lumbar disc tissues remains unclear. The aim of the present study was to detect telomerase expression in nucleus pulposus tissues of degenerative lumbar discs and to explore the correlation between telomerase expression and other factors typical of disc degeneration. A total of 8 patients with degenerative nucleus pulposus were included as the experimental group and compared with 8 control patients without evident lumbar disc degeneration. The expression of telomerase in nucleus pulposus tissues was detected by immunohistochemical staining. ELISA was performed to determine the differential expression of telomerase, type II collagen and chondroitin sulfate between the two groups. In addition, a correlation analysis was performed to form associations between these factors. Finally, 5 cases in the experimental group and 5 in the control group were involved in the analysis. Immunohistochemistry results showed that telomerase expression in the experimental group was significantly lower compared to the control group and the percentage in the unit field of view showed significant differences between the two groups (P<0.05). Similarly, the ELISA test results showed lower expression levels of telomerase, type II collagen and chondroitin sulfate in the experimental group when compared with the control group (P<0.05). The correlation analysis revealed that telomerase was positively correlated with type II collagen and chondroitin sulfate (correlation coefficients, 0.673 and 0.528, respectively; P<0.01). In conclusion, telomerase is involved in the degeneration process of nucleus pulposus tissue in lumbar discs and has a positive correlation with other factors typically associated with degeneration.
