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

Background/purpose: Successful long-term outcomes of one-step implant placement in the atrophic maxilla have rarely been reported. This retrospective study aimed to evaluate the long-term efficacy of the one-step lateral sinus floor elevation and simultaneous implant placement (LSFESI) in severely atrophic posterior maxilla, and to identify the risk factors for marginal bone loss (MBL) and late implant failure (LIF). Materials and methods: Clinical data were obtained from Taipei Tzu Chi Hospital. One-step, non-submerged LSFESI was performed at sites with a remaining bone height (RBH) Results: A total of 122 implants were placed in 60 patients across 73 sinuses to support fixed prosthetic reconstructions. The mean duration was 10 years. Implant survival rates were significant associated with several factors, including keratinized tissue (KT) Conclusion: This study demonstrated that one-step LSFESI can be a predictable approach with favorable long-term outcomes.
