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

INTRODUCTION/

aimsRespiratory failure from hypoventilation is the most common cause of death in amyotrophic lateral sclerosis (ALS). However, ALS care rarely assesses hypercapnia, a physiologic measure of hypoventilation. We investigated the prevalence and clinical significance of daytime hypercapnia measured by transcutaneous carbon dioxide (tcCO

methodsThis retrospective study included patients seen at two ALS clinics in the United States between 2012 and 2024 who had tcCO

resultsDaytime hypercapnia was present in 33/328 (10%) patients at baseline. Hypercapnia was associated with an increased rate of death (aHR 2.1, 95% CI 1.4-3.3). Orthopnea or dyspnea was 70% sensitive for hypercapnia (95% CI 51%-84%). Absolute value of MIP (|MIP|) < 60 cmH DISCUSSION: TcCO
