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

purposeInferior alveolar nerve transection (IANT) is a severe complication of sagittal split osteotomy (SSO). This study aimed to retrospectively evaluate the long-term sensory recovery in patients who experienced intraoperative IANT compared to those who did not. MATERIALS AND

methodsThis retrospective cohort study reviewed patients who underwent SSO from 2016 to 2022. Patients were divided into Group A (with IANT, 11 sides) and Group B (without IANT, 151 sides). Sensory perception was assessed using the Semmes-Weinstein (SW) test, static two-point discrimination (s-2PD) test, and a Numerical Rating Scale (NRS) at preoperative baseline and at 1, 3, 6, and 12 months postoperatively. Mann-Whitney U and Dunnett's tests were used for statistical analysis (p < .05).

resultsGroup A demonstrated significantly worse sensory outcomes than Group B on all tests at all postoperative time points (p < .01). In Group B, SW and s-2PD values were significantly worse than baseline at 1 and 3 months but showed no significant difference at 6 and 12 months. In contrast, Group A outcomes remained significantly impaired compared to their own preoperative baseline throughout the 12-month follow-up.

conclusionsComplete IANT during SSO, even with immediate nerve repair, results in a substantial and long-term persistent neurosensory deficit. While patients without nerve transection typically recover baseline sensory perception by 6 months, those with IANT experience only minimal improvement and remain significantly impaired at a year post-surgery.
