Clinical findings, prognostic factors, and outcome of protein-losing nephropathy in cats: A retrospective study.
Article in Journal of veterinary internal medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
backgroundPrimary glomerular disease resulting in protein-losing nephropathy (PLN) is an uncommon cause of chronic kidney disease in cats, yet is important to recognize because it warrants specific treatment that impacts outcome. HYPOTHESIS/
objectiveCharacterize clinicopathologic findings, prognostic indicators, and short- (≤30 days) and long-term survival of cats with PLN. ANIMALS: Thirty-seven cats with naturally occurring PLN.
methodsMedical records of cats with PLN admitted to a veterinary teaching hospital were retrospectively reviewed.
resultsMedian age was 3 years (range, 1.5-11.5 years) and 17/37 (46%) were males. Short-term survival was 57%. The estimated median survival time of all cats was 424 days (95% confidence interval [CI], 0-1098 days). Common clinical signs included lethargy (57%), edema (46%) and weight loss (35%). Edema was more common in short-term survivors compared with nonsurvivors (odds ratio [OR], 0.21; 95% CI, 0.05-0.86-20.4; P = .04). Serum creatinine concentration at presentation was negatively associated with long-term survival (OR, 1.3; 95% CI, 1.03-1.52; P = .01). Administration of immunosuppressive and antiproteinuric medications was more common among short-term survivors compared with nonsurvivors (18/20 [90%] vs 9/16 [56%]; OR, 7.0; 95% CI, 1.2-40.8; P = .05 and 17/20 [85%] vs 7/16 [44%]; OR, 7.3; 95% CI, 1.5-35.2; P = .01, respectively). Partial or complete remission was documented in 11/31 (36%) cats and was associated with both short (OR, 3.3; 95% CI, 1.7-6.5; P < .001) and long-term survival (P = .003). CONCLUSION AND CLINICAL IMPORTANCE: Cats with PLN have a guarded prognosis, but achieving remission improves outcome. Cats presented with edema rather than azotemia are more likely to respond to treatment.
