Electrolyte Concentration in Urine and Urinary Infection-Is There Any Relation?
Article in Biomedicines, 2025. 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
backgroundSodium, potassium, chloride, calcium, and magnesium in urine are useful biomarkers and are commonly evaluated in patients with different conditions. Urinary tract infections are among the most common diseases worldwide. However, their treatment poses significant challenges, particularly in hospitals, primarily due to antibiotic resistance and recurrence.
objectivesTo evaluate the relationship between ion concentrations in urine and the presence of infection.
methodsA total of 175 random urine samples were collected from patients who had a request for urine culture at the Cova da Beira University Hospital Centre in Portugal. In vitro contamination was also conducted, in which ten negative urine cultures were contaminated with an
resultsIn total, 61 samples were found to be positive, following a consensual quantitative definition. For Ca, there was a significant association between its concentrations in positive and negative cultures. In ten negative urine cultures experimentally contaminated with an
conclusionsThe presence of higher concentrations of Ca may facilitate the multiplication of Gram-negative bacteria, which can potentially result in depletion of Ca in vivo to putatively potentiate an inflammatory response. The concentration of Na, K, Cl, and Mg does not seem to have any relationship with UTIs.
