The Impact of Fan-Type Rapid Palatal Expanders on Speech in Patients With Unilateral Cleft Lip and Palate.

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.
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
Rapid palatal expanders (RPEs) are commonly used in patients with cleft lip and palate (CLP) prior to secondary alveolar bone grafting (SABG). Their position and size can impede tongue movement and affect speech. This study assessed changes in perception and production of speech over the course of RPE treatment. Prospective longitudinal. Tertiary university-affiliated hospital. Twenty-five patients with unilateral CLP treated with Fan-type RPEs, and their parents. Patient and parent speech questionnaires and patient speech recordings were collected at baseline before RPE insertion (T1), directly after RPE insertion (T2), during RPE expansion (T3), during RPE retention (T4), directly after RPE removal but before SABG (T5), and at short-term follow-up after RPE removal and SABG (T6). Ratings for patient and parent questionnaires, first (F1) and second (F2) formants for vowels /a/, /i/, and /u/, and nasalance scores for non-nasal and nasal sentences, were obtained and analyzed using mixed model analyses of variance. Ratings worsened at T2. For the vowel /a/, F1 and F2 were unchanged at T2. For the vowel /i/, F1 increased and F2 decreased at T2. For the vowel /u/, F1 was unchanged and F2 decreased at T2. Nasalance was unchanged at T2. All outcome measures returned to T1 levels by T4. RPE insertion resulted in initial adverse effects on speech perception and production, which decreased to baseline prior to removal. Information regarding transient speech dysfunction and distress may help prepare patients for treatment.
