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

objectivesTo generate synthesized information on the epidemiology of VZV infection, as well as an estimation of prevalence of age-specific antibody in Iranian less than 40. MATERIAL AND

methodsAfter exclusion of irrelevant and overlapping reports, 15 papers were included (from nine major cities). Studies were pooled according to the heterogeneity test results. Random effect model methods were used for meta-analysis where significant heterogeneity was observed (age 1-16years).For other age groups, fixed model were used.

resultsSignificant heterogeneity was observed in prevalence rates of all childhood age-groups. The seropositivity prevalence increased steeply from the age of 1-5 to 6-10 [from 21.9% (95% CI; 10.8-33.1) to 42.1 %(95% CI; 33.6-50.6)]. At the age of 11 15, 59.4% (95% CI; 46.1-72.8) of children showed to be infected. The rate of seropositivity was more than 87% in individuals of 40 and older.

conclusionThe varicella seroeprevalence in Iran is in accordance with average tropical and temperate areas. Comparison of conducted studies during 2003 to 2011 didn't show any alteration in VZV seroprovalence in Iran.
