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

objectivesCompare the long-term outcomes of alveolar bone and gingiva between the modified periodontally accelerated osteogenic orthodontics (PAOO) and the mainstream approach.

methodsThis retrospective study included 28 orthodontic patients with bone fenestration and dehiscence in the lower anterior teeth. Fourteen patients were treated with the modified PAOO approach, and 14 patients received the mainstream PAOO treatment. Alveolar bone and gingival conditions were evaluated preoperatively (T0), one week (T1), one year (T2), three years (T3), and five years post-surgery (T4).

resultsAt T4, the measured change in labial cervical third bone thickness (La-CHBT) of the modified group (0.99; 95% CI: 0.70 to 1.28 mm) was notably greater than that of the control group (0.16; 95% CI: -0.10 to 0.41 mm) (p < 0.001). Additionally, the modified group presented a lower bone graft absorption rate (BGAR) of 0.34 (95% CI: 0.24 to -0.55) versus 0.69 in the control group (95% CI: 0.58 to 0.80; p < 0.001). With respect to the gingival recession (GR), the modified method significantly reduced gingival recession from T0 to T4 (ΔT4 = -0.89; 95% CI: -1.21 to 0.44 mm); however, the GR at T4 in the control group was similar to that of T1 (ΔT4 = -0.14; 95% CI: -0.41 to 0.12 mm). The keratinized gingiva width (KGW) of the modified group increased 2.21 mm (95% CI: 1.52 to 2.91 mm), whereas the change in the control group was 0.11 mm (95% CI: -0.44 to 0.65 mm) (p < 0.001).

conclusionsIn terms of long-term outcomes, the modified method demonstrates superior performance in alveolar bone and gingival augmentation, outperforming the mainstream method. CLINICAL TRIAL NUMBER: Not applicable.
