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

purposeThe Global Voice Prevention and Therapy Model (GVPTM) with the Estill Voice Model (EVM) involves four concepts: 1) training multiple new voice targets to meet all the vocal demands of the client, 2) using an integrated implicit-explicit instructional approach, 3) switching between voice targets, and 4) facilitating voice practice in a bottom-up speech hierarchy. As a preliminary investigation into the four concepts, the current study compared the GVPTM with EVM to a modified version of the GVPTM (MGVPTM) with EVM that eliminated concepts 1 (only one new resonant voice was trained) and 3 (no switching between voice targets) and kept concepts 2 and 4.

methodsFour professional teachers were randomized into one of two conditions in a single-subject design counterbalanced with alternating treatments and baselines (ie, A
