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

At the time of this study, there were five known patients with Wilson disease (WD) in Iceland. The mutation, a 7-bp deletion in exon 7 on chromosome 13 for WD, is only known in Iceland. In twenty healthy Icelandic heterozygotes for WD and their age- and gender-matched controls, copper concentration in plasma, ceruloplasmin (CP) concentration, CP oxidative activity and CP-specific oxidative activity in serum and superoxide dismutase (SOD1) activity in erythrocytes were determined. The same determinations were done on the five WD patients. There was no significant difference in these parameters between the heterozygotes and the controls, although an inclination toward lower CP determinations and higher SOD1 activity in the heterozygotes was noted. As expected the WD patients were low on the copper and CP parameters, but their SOD1 activity was within the upper normal range. In conclusion, the CP parameters and SOD1 activity are within the normal range in Icelandic heterozygotes for WD, although with a trend toward mild dyshomeostasis. This may indicate subclinical copper retention in the heterozygotes, but a bigger study group is needed to confirm this.
