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
Background Renin-angiotensin-aldosterone (RAAS) blockade is acclaimed, by consensus, to be renoprotective in both diabetic and non-diabetic chronic kidney disease (CKD). Contradictory reports exist regarding renal and cardiovascular outcomes after stopping RAAS blockade in advanced CKD. A few prospective, non-randomized, cohort studies have demonstrated improvement in kidney function after discontinuation of RAAS blockade. In this study, we investigated renal and mortality outcomes following the elective withdrawal of RAAS blockade after otherwise inexplicable acute kidney injury (AKI). Methodology We conducted a retrospective cohort analysis of patients enrolled between February 2018 and May 2021. Kidney function was monitored after elective withdrawal of long-term RAAS blockade in CKD patients presenting with new-onset otherwise inexplicable progressive AKI, defined by a >25% increase in baseline serum creatinine. Results In total, 71 patients, 69 Caucasians, one African American, and one Hispanic, were included in the study, with a male-to-female ratio of 42:29, and a mean age of 69.4 (37-95) years. Through February 2022, 12 patients had died, with eight remaining on hemodialysis for end-stage renal disease. Of the remaining 51 patients followed for 706 (40-1,478) days, baseline serum creatinine was 1.30 ± 0.42 (0.66-2.70) mg/dL, peak enrollment serum creatinine was 2.17 ± 1.06 (1.1-8.3) mg/dL (n = 51, p < 0.0001, t = 6.4872, df = 135), and serum creatinine after four years was 1.58 ± 0.54 (0.84-3.3) mg/dL (n = 50, p < 0.0001, t = 5.1805, df = 119). Death in 11 of 12 (91%) patients was from non-renal causes, and most deaths occurred despite improved kidney function. Conclusions Our results demonstrate clearly improved renal outcomes in most patients following the elective withdrawal of long-term RAAS blockade in CKD patients with new-onset progressive yet otherwise inexplicable AKI without increased cardiovascular mortality.
