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

Weight loss is an independent predictor of survival in the early stages of amyotrophic lateral sclerosis (ALS). However, the effects of weight variations on the functional prognosis after tracheostomy and invasive ventilation (TIV) in ALS remain unknown. This prospective cohort study aimed to investigate the relationship between weight loss before TIV and disease progression after TIV in ALS patients. Sixty ALS patients with TIV were enrolled and classified into subgroups based on the rate of decline in body mass index, from onset to TIV utilization (ΔBMI). During follow-up, we assessed the patients for presence of communication impairments, ophthalmoplegia, total quadriplegia, mouth opening disability, and dysuria. We analyzed the relationship between ΔBMI and the communication stage or motor disabilities. The log-rank test showed that patients with a ΔBMI ≥ 1.7 kg/m
