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

aimThis retrospective cohort study aimed to identify pretreatment prognostic factors for tooth survival in teeth with endodontic-periodontal lesions (EPLs). MATERIALS AND

methodsTeeth with EPLs treated according to a standardised clinical protocol involving periodontal and endodontic treatments were included. Clinical parameters were measured, and the EPL grade was classified according to the 2017 World Workshop criteria. Based on the radiographic characteristics, lesions were categorised as I-shaped (unilateral intrabony defect without apparent apical radiolucency), J-shaped (unilateral intrabony defect with apical radiolucency) and U-shaped (bilateral intrabony defects with apical radiolucency). Survival-time analysis was performed.

resultsOf the 187 teeth included, 117 survived over the mean observation period of 3.1 ± 2.1 years (maximum, 8.4 years). The estimated 1- and 5-year tooth survival rates were 83.8% and 58.9%, respectively. Multivariate analysis identified age, EPL grade, probing depth (PD), periapical index, bone loss and I-J-U subclassification as significant prognostic factors for tooth survival. The I-J-U subclassification was significantly associated with tooth survival, suggesting its potential value in prognostic assessment.

conclusionThis retrospective cohort study identified age, EPL grade, PD and radiographic shape of bone loss as predicting factors for tooth survival in teeth with EPLs.
