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

objectivesRising demands for aesthetic outcomes make precise preoperative assessment essential. Despite advances in digital workflows, their accuracy versus conventional techniques remains uncertain. The current study comparatively assessed the trueness of digitally- and conventionally-fabricated mockups. MATERIALS AND

methodsFourteen patients needing ceramic veneers in the anterior maxilla participated. Each received three mockups: one fabricated conventionally and two digitally (additive and subtractive). The mockups were placed intraorally and scanned. The scans were superimposed on a reference model to evaluate the accuracy of the entire workflow and on the reference wax-up to assess production accuracy. Data were analyzed by paired samples test, repeated measures ANOVA, Bonferroni test, and generalized estimating equation (GEE) (α = 0.05).

resultsFor the whole production process, the root mean square (RMS) was 0.13 (0.04) for the conventional method, which was significantly lower than that for the additive as 0.60 (0.07) and subtractive of 0.51 (0.07) digital techniques (p < 0.001). Also, for the production phase, the mean RMS of different methods was significantly different (p < 0.001). The conventional method showed the lowest mean by 0.22 (0.07), and the additive technique showed the highest mean by 0.76 (0.02) RMS. The mean RMS was 0.73 (0.02) for the subtractive method.

conclusionsThe trueness of the conventional method was higher than that of the digital method for both the whole production process and the production phase. The conventional method significantly decreases the chairside time especially when tooth surface treatment is not required. The trueness of the subtractive method was higher than that of the additive method.
