Predictive value of Prognostic Nutritional Index (PNI) for the severity of vasculogenic erectile dysfunction.

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
purposeOur aim was to investigate the association of prognostic nutritional index (PNI) score with erectile dysfunction (ED), therefore, we prospectively evaluated the relationship between penile doppler ultrasonography (PDU) findings, PNI and Sexual Health Inventory for Men (SHIM) scores in patients with ED.
methodsA total of 414 patients' characteristics, laboratory findings, SHIM and PNI scores were recorded. The PNI is calculated using the formula: 10 × serum albumin + 0.005 × total lymphocyte count. PDU was performed in patients with a SHIM score of 17 and below, while patients with a SHIM score ≥ 18 were recruited for the control group. Correlation analysis was performed to evaluate the relationship between PNI, SHIM scores and PDU parameters. The predictive value of variables for severe ED was assessed with regression analysis.
resultsA significant difference was demonstrated between the ED subgroups and control group for total cholesterol (p = 0.04), serum albumin (p = 0.03), total lymphocyte count (p = 0.02), BDI score (p < 0.001), and PNI score (p = 0.03). A strong positive correlation between PNI score and PSV (rho = 0.73; p = 0.001), a moderate negative correlation between PNI score and EDV (rho = - 0.54; p = 0.02), and a moderate positive correlation between PNI and SHIM scores (rho = 0.61; p = 0.02) were demonstrated. PNI score ≤ 40 (OR: 3.49; p = 0.01), age (OR: 2.15; p = 0.03) and total cholesterol (OR: 2.03; p = 0.04) were determined as significant predictors of severe ED in multivariate analysis.
conclusionOur results demonstrated that PNI score is significantly lower in patients with severe and moderate ED. It has been also revealed that the PNI score is an independent predictive factor for severe ED.
