Characterization of the intrarenal renin-angiotensin system in cats with naturally occurring chronic kidney disease.
Article in Journal of veterinary internal medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundThe role of the renin-angiotensin-aldosterone system in cats with chronic kidney disease (CKD) is incompletely understood.
objectiveTo characterize components of the intrarenal renin-angiotensin system (RAS) in cats with CKD. ANIMALS: Eleven cats with naturally occurring CKD (CKD group) and 8 healthy control cats.
methodsRenal tissue samples were evaluated by reverse-transcription polymerase chain reaction for renin, angiotensinogen, angiotensin-converting enzyme (ACE), and angiotensin II type 1 receptor transcript levels, and by liquid chromatography-mass spectrometry for quantification of angiotensin I, II, III, and IV concentrations. Linear mixed models were used to compare gene transcript levels and concentrations of angiotensin peptides between groups.
resultsCats of the CKD group were significantly older (P < .001) and more likely to be neutered (P = .007) than healthy control cats. Kidneys from cats with CKD had significantly higher transcript levels of angiotensinogen (P < .001) and lower transcript levels of ACE (P < .001) than those from control cats. Renal angiotensin I concentrations were increased in CKD compared with control kidneys (P = .001). No other significant differences in renal transcript levels or angiotensin peptide concentrations were noted between groups. CONCLUSION AND CLINICAL IMPORTANCE: The intrarenal RAS might be activated in cats with CKD. Small sample size and differences in age, neuter status, and dietary sodium intake between groups might have limited the ability to identify a significant difference in concentration of renal angiotensin II.
