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

purposeAcoustic analysis is an objective and quantitative method in diagnosing speech disorders and evaluating treatment efficacy. Although many reports have used acoustic analysis for oral cancer patients, few studies have focused on the extent of tongue resection. The aim of this study was to evaluate the usefulness of acoustic analysis in the assessment of postoperative speech impairment in oral cancer patients.

methodsPostoperative speech data as well as Speech Handicap Index (SHI) and 5-point speech intelligibility scale were collected from 65 patients including 31 cases of oral cancer resection without glossectomy, 18 cases of partial glossectomy, and 16 cases of subtotal glossectomy. Speech data were acoustically analyzed by triangular vowel space area, vowel articulation index (VAI), first (F1) and second (F2) formant slopes, and compared according to the extent of tongue resection.

resultsThe frequency of speech impairment assessed by SHI and 5-point speech intelligibility scale was differed according to the extent of tongue resection. As acoustic analysis, VAI and F1 slope in cases of subtotal glossectomy were significantly smaller than those in cases of partial glossectomy. F2 slope in cases of subtotal glossectomy was significantly smaller than those in the other cases.

conclusionAcoustic analysis was potentially useful as an objective speech assessment for the patients who underwent oral cancer surgery.
