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

BACKGROUND/

objectivesThis study aimed to investigate the effect of tibolone (TIB) on the expression of the NOX2 and NOX4 isoforms and their co-localization in neurons and astrocytes using an animal model of spinal cord injury (SCI).

methodsMale Sprague Dawley rats were subjected to contusive SCI at T9 and treated with TIB (1 or 2.5 mg/kg/day). The expression of NOX2 and NOX4, and their co-localization in neurons and astrocytes, were evaluated at 3, 7, and 15 days post-SCI. Oxidative stress markers and motor recovery were also assessed.

resultsSCI induced a time-dependent increase in NOX2 protein expression at 15 days compared to 3 days (0.192 ± 0.012 vs. 0.013 ± 0.0007) and in NOX4 protein expression (0.027 ± 0.002 vs. 0.958 ± 0.088), displaying differential cell-specific localization patterns in neurons and astrocytes across time points. TIB treatment significantly attenuated SCI-induced oxidative stress (15,391.8 ± 1047.6 vs. 21,264.4 ± 2669.8) and decreased NOX2 and NOX4 co-localization in both neurons and astrocytes in a dose- and time-dependent manner. Furthermore, TIB-treated animals exhibited a modest but significant restoration of motor function at 15 days post-SCI.

conclusionsOur findings indicate that TIB administration reduces oxidative stress, modifies NOX2 and NOX4 immunoreactivity patterns in neurons and astrocytes, and promotes partial functional recovery following SCI.
