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

backgroundPrevious studies have shown that elosulfase alfa has a favorable efficacy/safety profile in Morquio A patients aged ≥5 y. This study evaluated safety and impact on urine keratan sulfate (uKS) levels and growth velocity in younger patients.

methodsFifteen Morquio A patients aged <5 y received elosulfase alfa 2.0 mg/kg/week for 52 wk during the primary treatment phase of a phase II, open-label, multinational study. Primary endpoint was safety and tolerability; secondary endpoints were change in uKS and growth velocity over 52 wk.

resultsAll 15 patients completed the primary treatment phase. Six of 743 infusions (0.8%) administered led to adverse events (AEs) requiring infusion interruption and medical intervention. Eleven patients (73.3%) had ≥1 study drug-related AE, mostly infusion-associated reactions. Mean z-score growth rate per year numerically improved from -0.6 at baseline to -0.4 at week 52. Comparison to untreated subjects of similar age in the Morquio A Clinical Assessment Program study showed a smaller decrease in height z-scores for treated than for untreated patients. Mean percent change from baseline in uKS was -30.2% at 2 wk and -43.5% at 52 wk.

conclusionEarly intervention with elosulfase alfa is well-tolerated and produces a decrease in uKS and a trend toward improvement in growth.
