Effects of polyunsaturated fatty acids (PUFAs) in the treatment of experimental chronic renal failure.
Article in International urology and nephrology, 2012. 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
purposeA diet with polyunsaturated fatty acid (PUFA) supplementation has been reported to reduce renal and cardiac diseases. This study sought to elucidate whether PUFAs derived from plant or marine oils could have beneficial effects on the progression of experimental chronic renal failure (CRF).
methodsExperimental CRF was achieved by a 5/6 nephrectomy model. Male Wistar rats were divided into groups and given daily supplements of fish oil (group FO), flaxseed oil (group FXO), or soybean oil (control-group SO) for 30 days. Serum creatinine (sCr), 24-h proteinuria, total cholesterol, triglycerides, and creatinine clearance (CLcr) were measured at day 0 and 30 days after surgery when the rats were euthanized for histological analysis of the remnant kidney.
resultsAfter 30 days, we observed lower levels of sCr in the groups supplemented with PUFA when compared with the control group (FO: 0.92 ± 0.13; FXO: 1.06 ± 0.28; SO: 1.32 ± 0.47 mg/dL) and significantly slower variations of sCr (ΔsCr) in the groups treated with PUFAs (FO = 0.35 ± 0.16; FXO = 0.47 ± 0.31; OS = 0.72 ± 0.43; mg/dL, P = 0.041). Similarly, the CLcr of both of the groups that received PUFAs was significantly slower than the rats in the control group (FO: 0.45 ± 0.15; FXO: 0.60 ± 0.09; SO: 0.28 ± 0.06 mL/min/day; P = 0.01). The rats that received PUFA supplements also presented significantly less histological lesions compared with the control group.
conclusionsThese results suggest a beneficial effect of dietary supplementation with flaxseed or fish oil in rats with CRF.
