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

objectivesThis RCT evaluated and compared the clinical performance of zirconia and titanium dental implants placed in the maxillary premolar region. Outcomes were assessed 3 years after prosthetic loading and included marginal bone level (MBL) changes, clinical parameters, aesthetic outcomes, and patient related outcome measures (PROMs). MATERIALS AND

methodsFifty patients were randomly allocated to receive either a zirconia one-piece (ZrO

resultsAfter 3 years, mean MBL change was -0.02 mm (SD = 0.78) for ZrO CONCLUSION AND CLINICAL IMPLICATIONS: After 3 years of function, the ZrO
