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

objectivesThe aim of this retrospective study was to evaluate implant stability using resonance frequency analysis (RFA) (Osstell MATERIALS AND

methodsAfter 3 months, 145 implants were evaluated for secondary implant stability using RFA. Of the evaluated implants, 72 were set in original bone (OB) in the upper posterior jaw, 21 were set in combination with a one-stage autologous external sinus floor elevation (EE), and 52 in combination with internal elevation (IE).

resultsOsseointegration was significantly higher in OB (94,4%) compared to EE (76,2%) and IE (80,8%). RFA values were best in the OB group (OB: 77,5 [8], EE: 75 [12], IE: 75 [8]; p = 0,030).

conclusionIn general, autologous one-stage sinus floor elevation combined with implantation is a safe procedure, but we recommend a prolonged healing phase of at least four additional weeks for EE and IE procedures. CLINICAL RELEVANCE: Although one-stage procedures require longer healing phases, treatment duration is still shorter than a two-stage procedure. Patients often prefer minimally invasive and short options because of anxiety and stress.
