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 large-scale retrospective study aims to evaluate and compare the long-term survival rates of dental implants placed immediately after tooth extraction (type 1) versus those placed at a later stage (types 2, 3, and 4). Additionally, it examines how patient characteristics and implant site conditions influence the choice of implant placement. MATERIALS AND

methodsThis study retrospectively analyzed patient data from 10 university dental clinics between 2011 and 2022 and examined dental implant treatment outcomes. Patient information, including age, sex, ethnicity, race, smoking, and medical status, was analyzed.

resultsRecords of 20,842 patients with 50,333 dental implants inserted between 2011 and 2022 were analyzed. The multivariate analysis resulted in significant differences for age, ethnicity, race, gender, and asthma. A 98.4% survival rate for dental implants placed immediately following extraction and a 98.6% survival rate for those placed in fully healed sockets were recorded. The type of implant placement (immediate vs. delayed) showed no significant effect on implant outcome.

conclusionImmediate implant placement resulted in high survival rates with delayed implants inserted into healed sites. Both immediate and delayed implant placements are viable therapeutic approaches demonstrating predictable outcomes.
