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

Introduction: Olfactory dysfunction is prevalent among individuals with chronic kidney disease (CKD), with prevalence escalating alongside disease severity. The uremic toxin we observed in this study is Indoxyl sulfate (IS), a potent uremic toxin that markedly accumulates in the plasma of patients with chronic insufficiency. Olfactory damage may occur in the setting of neuronal damage due to renal failure. Materials and Methods: 27 patients, a total sample in this study with diagnosed chronic kidney disease within stage 5 on regular hemodialysis, were examined for indoxyl sulfate levels in blood plasma and then examined for their olfactory function using the Sniffin' Sticks test. A correlation analysis was conducted between indoxyl sulfate levels and olfactory function test results in patients with CKD. Results: The Pearson correlation test revealed a strong, significant negative correlation between indoxyl sulfate levels and olfactory function (r = -0.613; p = 0.001). Additionally, correlations were found between indoxyl sulfate levels and each component of olfactory function: threshold value (r = -0.408; p = 0.035), discrimination (r = -0.807; p = 0.001), and identification (r = -0.703; p = 0.001). Conclusion: Olfactory function is compromised in individuals with chronic renal disease and correlates with the level of accumulation of the uremic toxin indoxyl sulfate.
