Prevalence of Hyponatremia Among Adult Patients on Antidepressant Medications in a Tertiary Care Hospital: A Cross-Sectional Study.

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
introductionThis study aimed to estimate the prevalence of hyponatremia associated with antidepressant medications.
methodsIt was a cross-sectional observational study conducted for a duration of two months. Patients visiting the psychiatry department and fulfilling the inclusion criteria were recruited into the study after explaining the study and obtaining their written informed consent. Patient data was collected in a case report form and compiled on Microsoft Excel sheets (Microsoft Corp., Redmond, WA, USA). Patients displaying abnormal electrolyte levels were studied closely for association between the class of antidepressants prescribed to them, the individual drugs, the gender of the patient, and any concomitant medical illness or medications. Possible associations and correlations were documented.
resultsIn our study sample, we observed that some patients taking the selective serotonin reuptake inhibitor (SSRI) class of antidepressant drugs displayed hyponatremia. Also, hyponatremia was seen only in the female patients of our study and not in the male patients. No association could be established with concomitant medical diseases or medications for developing hyponatremia in patients taking antidepressant drugs possibly due to the small sample size. Prevalence of hyponatremia was 2.65% with 95% CI in patients taking any antidepressant medication, while it was 3.5% in patients taking drugs of the SSRI class.
conclusionsWe conclude that more detailed and larger studies are required to establish an association between hyponatremia and antidepressant drugs, especially with SSRIs. Going forward, we suggest monitoring of serum sodium levels in patients who are prescribed antidepressant drugs.
