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 evaluate the 2-4-year clinical performance of lithium disilicate ceramic occlusal veneers for restoring vital cracked teeth and to explore factors associated with restoration failure. MATERIALS AND

methodsA prospective study was conducted on 60 cracked teeth from 51 patients. All restorations were evaluated according to the modified United States Public Health Service (USPHS) criteria: (a) marginal discoloration, (b) secondary caries, (c) restoration fracture, (d) adjacent contact point loosening, and (e) smoothness of adjacent areas. Risk factors were analyzed using χ² tests, Kaplan-Meier analysis, and univariate Cox proportional hazards regression.

resultsThe restoration survival rate was 95% (57/60), and the restoration integrity rate was 85% (51/60). A total of 9 restorations met the broader failure definition used for exploratory risk-factor analysis, including 3 severe fractures requiring remaking and 6 marginal defects requiring repair. Among 60 occlusal veneers, none had severe discoloration or secondary caries. The worst scores for adjacent contact point loosening and surface smoothness were 5% (3/60) due to 3 restorations with severe fractures. Second molars showed a significantly higher risk of restoration failure compared with other teeth (χ

conclusionsOcclusal veneers showed favorable medium-term restoration outcomes for restoring cracked teeth, with a high success rate observed over a 2-4-year follow-up period. CLINICAL RELEVANCE: This study aims to help clinicians optimize the treatment planning of cracked teeth and improve the long-term success of occlusal veneer restorations.
