Experimental sciatic nerve neuropathy caused by diclofenac sodium in rats.
Article in Northern clinics of Istanbul, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveOur aim in this study is to investigate the total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values of diclofenac sodium, which is a non-steroidal anti-inflammatory analgesic, after sciatic nerve injury, to examine the histopathological changes in the sciatic nerve, and to examine the results and enable important changes in treatment. It is one of the rare studies conducted histopathologically on post-injection sciatic nerve damage of diclofenac sodium, and the parameters of our biochemical approach have not been evaluated before in the literature.
methodsstudy was divided into 5 main groups as control, sham, trauma, isotonic fluid, and diclofenac sodium. Sham, trauma, isotonic fluid, and diclofenac sodium groups were divided into four subgroups as early stage (day 1, day 3) and late stage (day 7 and day 14). Subjects in each group were evaluated daily by neurological examination according to the Tarlov scale. In all groups except the control group, the sciatic nerve was exposed through appropriate surgical procedures. TAS, TOS, and OSI were run on blood samples biochemically. Nerve tissue samples were evaluated histopathologically and immunohistochemically.
resultsThere was a significant difference in pairwise comparison of the groups in terms of CASPASE-3 values. A statistically significant difference was found between the groups in terms of myelin thickness and axon diameter. A statistically significant difference was found between the groups in terms of nerve diameter values.
conclusionOur study demonstrates that intramuscular injections of diclofenac sodium have potential harmful effects. We recommend that alternative methods of using diclofenac sodium intramuscularly be preferred whenever possible due to the potential complications associated with this drug, that healthcare professionals receive necessary training on intramuscular administration, that the procedures be performed more carefully, and that patients be informed about these complications.
