Analgesic effect of duloxetine compared to nortryptiline in patients with painful neuropathy: A randomized, double-blind, placebo-controlled trial.
Article in Caspian journal of internal medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 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
backgroundDiabetic neuropathic pain (DNP) is a common complication of diabetes and has a profound effect on patients' quality of life. Therefore. The purpose of the present study was to compare the analgesic effects of duloxetine and nortryptiline in the management of patients with diabetic neuropathy.
methodsThis was a randomized, double-blind, parallel-group, placebo-controlled trial in subjects with a proven diagnosis of DM and suffered from neuropathic pain
resultsBoth drugs reduced pain when compared with placebo. A significant VAS reduction from 6.4 at baseline to 3.75 at endpoint was observed in the duloxetine group. However, there was no significant difference in the efficacy between nortriptyline and duloxetine based on patient's visual analogue scale (VAS) (p>0.05). No clinically significant changes or serious adverse events were found among treatment groups including changes in vital signs, laboratory assessments, physical examination or electrocardiograms. The decrease in the mean pain intensity was significantly greater in the duloxetine and nortriptyline group compared to the placebo group both in the primary analysis and in the by-visit analysis (p<0.003).
conclusionThe present study demonstrates the safety and effectiveness of both duloxetine and nortriptyline in the management of DNP.
