Efficacy and Safety of Ion Channel Modulators in Painful Diabetic Neuropathy.
Synthesis in Diabetes, obesity & metabolism, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
aimsTo systematically evaluate the efficacy and safety of ion channel modulators for the treatment of painful diabetic neuropathy (PDN). MATERIALS AND
methodsWe searched PubMed, Web of Science, Embase, and the Cochrane Library for randomized controlled trials (RCTs) in PDN patients treated with ion channel modulators. The primary outcome was the pain score. Secondary outcomes included the visual analog scale (VAS) score, 30% and 50% pain reduction, patient global impression of change (PGIC), sleep interference score, adverse events, and treatment discontinuation. Independent authors extracted the data and assessed the quality. Heterogeneity among studies was quantified using the I
resultsA total of 36 RCTs comprising 6611 participants with PDN were included in the analyses, of which 21 were evaluated with calcium channel blockers, 12 with sodium channel blockers, 2 with TRPA1 antagonists, and 1 with P2X3 antagonists. Compared with placebo, ion channel modulators, particularly calcium channel blockers (mirogabalin, pregabalin, gabapentin, crisugabalin) and sodium channel antagonists (oxcarbazepine, lacosamide, lamotrigine, sodium valproate), can significantly reduce pain, VAS, and sleep interference scores, improve PGIC, and increase the proportion of patients achieving 30% and 50% pain reduction. The therapeutic effects of the TRPA1 antagonists and P2X3 antagonists did not differ significantly from those of the control. The adverse events of ion channel modulators were mild to moderate and well tolerated, but the risk of discontinuation due to adverse events was higher with mirogabalin and oxcarbazepine than with the other modulators.
conclusionIon channel modulators, especially calcium channel blockers and sodium channel antagonists, have favourable safety profiles and beneficial effects on reducing pain and improving the quality of life of patients with PDN.
