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
objectiveThis study was carried out to evaluate the relationship between dietary and serum zinc and leptin levels with protein-energy wasting (PEW) in haemodialysis patients.
methodsThe study was conducted on 80 volunteer patients aged 19-65 years who received haemodialysis treatment three times a week for at least 1 year. Anthropometric measurements and body composition analyses were performed. Blood samples were collected for serum zinc and leptin and other biochemical parameters. Food consumption of the patients was recorded for 3 days. Malnutrition-inflammation score (MIS) was calculated for all patients. PEW was assessed according to the criteria recommended by the International Society of Renal Nutrition and Metabolism (ISRNM).
resultsAccording to the ISRNM criteria, 38.1% of male patients and 36.8% of female patients were diagnosed with PEW. The median serum leptin levels of patients with PEW [9.0 (16.9) ng/mL] were significantly lower than those without PEW [20.7 (38.5) ng/mL] (p < 0.05). Dietary zinc intake in patients with PEW was significantly lower than that in patients without PEW (p < 0.05). However, there was no significant difference in serum zinc levels between the patients with and without PEW. In the multivariate analyses, dietary and serum zinc and leptin was associated with PEW. After controlling for several confounding factors these associations disappeared. Dietary zinc intake and serum leptin levels were inversely correlated with MİS. There was no relationship between serum leptin and dietary and serum zinc in these patients.
conclusionDietary zinc intake and serum zinc and leptin concentration were not associated with PEW. Low serum leptin levels might be the outcome rather than the cause of PEW in haemodialysis patients.
