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

People in regions of Schistosoma mansoni endemicity slowly acquire immunity, but why this takes years to develop is still not clear. It has been associated with increases in parasite-specific IgE, induced, some investigators propose, to antigens exposed during the death of adult worms. These antigens include members of the tegumental-allergen-like protein family (TAL1 to TAL13). Previously, in a group of S. mansoni-infected Ugandan males, we showed that IgE responses to three TALs expressed in worms (TAL1, -3, and -5) became more prevalent with age. Now, in a subcohort we examined associations of these responses with resistance to reinfection and use the data to propose a mechanism for the slow development of immunity. IgE was measured 9 weeks posttreatment and at reinfection at 2 years (n = 144). An anti-TAL5 IgE (herein referred to as TAL5 IgE) response was associated with reduced reinfection even after adjusting for age using regression analysis (geometric mean odds ratio, 0.24; P = 0.016). TAL5 IgE responders were a subset of TAL3 IgE responders, themselves a subset of TAL1 responders. TAL3 IgE and TAL5 IgE were highly cross-reactive, with TAL3 the immunizing antigen and TAL5 the cross-reactive antigen. Transcriptional and translational studies show that TAL3 is most abundant in adult worms and that TAL5 is most abundant in infectious larvae. We propose that in chronic schistosomiasis, older individuals have repeatedly experienced IgE antigens exposed when adult worms die (e.g., TAL3) and that this leads to increasing cross-reactivity with antigens of invading larvae (e.g., TAL5). Progressive accumulation of worm/larvae cross-reactivity could explain the age-dependent immunity observed in areas of endemicity.
