ALSFRS-R score and its ratio: A useful predictor for ALS-progression
Abstract
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder. To determine predictors of survival, we studied different parameters in our ALS Database including 479 patients. The effects of individual prognostic factors of survival were studied using Kaplan-Meier life table. The prognostic value of each factor of interest was expressed in terms of a hazard ratio. Survival from symptom-onset ranged from 4 months up to 11.9 years. Gender had no effect on survival in our cohort. However, age, site of onset, forced vital capacity, symptom duration and ALSFRS-R score at the first visit were independent prognostic factors in our population (log-rank p<0.01). The ratio of ALSFRS-R score between first symptom and first examination, during whole disease or within 100 days, correlates with survival time. We conclude that the ratio of ALSFRS-R score within 100 days is a useful parameter for clinical trials and daily clinical work in a tertiary ALS-clinic.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
