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

This 30-mo double-blind randomized clinical superiority trial aimed to assess the effectiveness of semiannual application of 38% silver diamine fluoride (SDF) solution in preventing early childhood caries in primary upper anterior teeth. The active comparator was 5% sodium fluoride varnish (FV). The primary outcome was the mean number of new carious tooth surfaces per child at the 30-mo follow-up. Children aged 3 to 4 y were block randomized to receive semiannual application of SDF or FV on their primary upper anterior teeth over a 30-mo period in kindergarten. Parents completed a validated questionnaire to collect information on child oral health-related behaviors and sociodemographic characteristics. In an intention-to-treat analysis, multilevel logistic regression with a generalized estimating equation (GEE) model was performed. At baseline, 730 children with 17,480 sound tooth surfaces were recruited (SDF group,
