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

introductionAmyotrophic lateral sclerosis (ALS) is the most common cause of motor neuron disease, and effective treatment for ALS is still lacking. Transactive response (TAR) -DNA-binding protein-43 (TDP-43) is aggregated in the neurons of ALS patients. Animal studies shown TDP-43 aggregation can be attenuated by enhancing autophagy by tamoxifen. However, its beneficial effects for ALS patients remain unknown.

methodsEighteen patients with ALS without mutations in superoxide dismutase-1 (SOD-1) or fused in sarcoma (FUS) genes were randomly assigned into the tamoxifen 40 mg/day or placebo group in a double-blinded manner and all were given riluzole twice daily. Participants were followed up at 1, 3, 6, and 12 months. The primary end point was time to death or dependence on mechanical ventilation. Secondary end points were decline of the revised ALS Functional Rating Scale (ALSFRS-R) score and pulmonary function measured by forced vital capacity (FVC).

resultsTen participants were randomly assigned in the treatment group with tamoxifen, 7 finished trial, 1 reach primary endpoint; while 8 participants in the placebo group, 2 finished trial and 2 reach primary end point. The proportion of participants reaching the primary end point was lower in the tamoxifen group but did not reach statistical significance. At the 1-, 3-, and 6-month follow-up, the average decline rates of the ALSFRS-R score were slower in the tamoxifen group. No significant difference was observed in FVC and ALSFRS-R score at 12 months between groups.

conclusionTamoxifen exerted only a modest effect on attenuate progression for 6 months in this small trial. Additional larger scale studies should be necessary to confirm whether enhancing autophagy can attenuate ALS progression.
