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

objectiveTo compare survival among patients with different combinations of apraxia of speech (AOS) and agrammatic aphasia, including those with isolated AOS (primary progressive AOS, PPAOS), both AOS and agrammatic aphasia (AOS + progressive agrammatic aphasia [PAA]), and isolated agrammatic aphasia (PAA).

methodsOne hundred nine patients were recruited who had any combination of AOS and agrammatic aphasia (42 PPAOS, 56 AOS + PAA, and 11 PAA) and were followed longitudinally, with 57 patients having since died. Cox proportional hazard models were used to quantify the relative risk of death across diagnoses. Adjusted survival curves are presented based on this model. We also assessed the influence of AOS and aphasia severity on survival.

resultsPPAOS had the longest survival (median survival of 5.97 years from the baseline visit), followed by PAA (5.26 years) and then AOS + PAA (4.33 years). AOS + PAA had a greater risk of death than PPAOS, with a hazard ratio of 3.01 (lower/upper confidence interval = 1.66/5.46,

conclusionsIndividuals with PPAOS have better survival and reduced risk of death compared with individuals with AOS + PAA. This finding will help improve prognostic estimates for these patients and supports the value of distinguishing PPAOS from AOS + PAA.
