1 · What the graph read from 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.

2 · The registry

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

backgroundAcute pyelonephritis is a common infection in children that may cause renal scarring. The aim of this systematic review and meta-analysis was to analyse the use of corticosteroid treatment to prevent renal scarring.

methodsWe searched the PubMED, SCOPUS, Cochrane CENTRAL and Web of Science databases in June 2022 for (corticosteroid* or dexamethasone or prednisolone* or prednisone* or hydrocortisone*) AND pyelonephritis. Randomised controlled trials focusing on children were included. The intervention was corticosteroid treatment with antibiotics compared to antibiotics with or without a placebo. The main outcome was the presence of renal scars on dimercaptosuccinic acid scanning at follow-up. The evidence quality was assessed using the GRADE methodology and risk of bias 2.0 tool. We calculated the risk ratio (RR), absolute risk difference (RD) with 95% confidence intervals (CI) and the number needed to treat (NNT). We applied a fixed effects model due to low heterogeneity.

resultsWe screened 872 abstracts and included five full texts. Renal scarring at follow-up was found in 31/220 (14.1%) patients in the corticosteroid groups and 76/278 (27.3%) in the control groups (RR 0.65, CI 0.44-0.96, RD - 13.2%, NNT 8). The evidence quality was moderate. Two studies reported adverse events with no differences between the groups. The risk of bias analysis showed some concerns in four studies.

conclusionWe found moderate quality evidence that adjuvant corticosteroid treatment could prevent renal scarring. Adverse events were insufficiently reported, and more research on their effectiveness and harm is therefore needed before using corticosteroids in clinical settings.
