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 and hypothesisA more pronounced short-term increase in single-kidney GFR (ΔskGFR) has been associated with better long-term kidney function in living kidney donors. Whether this also applies to non-donors is unknown. We evaluated whether ΔskGFR is associated with long-term risk of eGFR decline in individuals undergoing unilateral nephrectomy.
methodsThis study included 1777 participants from the SCREAM cohort who underwent radical unilateral nephrectomy in Stockholm between 2006 and 2021. The ΔskGFR was calculated as the early (1-6 months) post-nephrectomy eGFR minus 50% of the pre-nephrectomy eGFR. Multivariable Cox regression was used to study the association between Δsk-GFR and the subsequent risk of progressive eGFR decline, defined as composite of an eGFR decline >30% compared to the early (6 months) post-nephrectomy eGFR or kidney failure.
resultsMean age at nephrectomy was 68 ± 11 years, 40% were female, 92% had kidney cancer, and median (IQR) pre-nephrectomy eGFR was 76 (61-89) ml/min/1.73 m2. Median Δsk-GFR was 11 (7-20) ml/min/1.73 m2. Pre-nephrectomy determinants of Δsk-GFR were age (inverse association) and pre-nephrectomy eGFR (positive association). During a median follow-up of 5 years (range 0.6-15 years), 178 participants developed progressive eGFR decline. Individuals with a Δsk-GFR above the median had a lower rate of progressive eGFR decline (adjusted HR: 0.58, 95% CI: 0.42-0.80), compared to those with a Δsk-GFR below the median, independent of baseline eGFR and age.
conclusionsA stronger increase in single-kidney eGFR early after unilateral nephrectomy was associated with a lower long-term risk of progressive eGFR decline. Evaluation of Δsk-GFR could help identify patients at higher risk of progressive kidney function decline following unilateral nephrectomy.
