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

objectivesThe primary objective was to estimate the proportion of children with frequently relapsing nephrotic syndrome (FRNS) and steroid-dependent nephrotic syndrome (SDNS) responding to oral cyclophosphamide, while secondary objectives were to document adverse effects, evaluate relapse-free survival following therapy, and assess outcomes at the last follow-up.

methodsIn this retrospective cohort study, 100 children aged 1-18 years with FRNS or SDNS who received oral cyclophosphamide (cumulative dose ≤168 mg/kg) between 2010 and 2023 at a pediatric nephrology clinic were included. Demographic characteristics, previous treatments, adverse effects, and relapse patterns were retrieved from medical records. Response was defined as being relapse-free and off steroids for ≥6 months after completion of cyclophosphamide therapy, while sustained remission was defined as absence of relapse for ≥2 years.

resultsThe median (q1, q3) age at onset of nephrotic syndrome was 4 (2.5, 6) years, and oral cyclophosphamide was initiated at 8 (7, 10) years. The response rate to oral cyclophosphamide was 67%, with a median (q1, q3) relapse-free interval of 9.1 (3.9, 24.7) months. Adverse effects occurred in 28%, most commonly nail discoloration (28 cases), followed by transient leukopenia (4 cases). During follow-up, 56% required an alternative steroid-sparing agent. At a median (q1, q3) follow-up of 72.5 (25.5, 107.25) months, 28% achieved sustained remission, while 69% had infrequent relapses.

conclusionOral cyclophosphamide is effective in children with FRNS and SDNS, inducing sustained remission in a significant proportion and suggesting a prolonged therapeutic effect. However, many children require additional immunosuppressive therapy during follow-up.
