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

Phosphoserine phosphatase (PSP) catalyzes the dephosphorylation of 3-phosphoserine, which is the final step in the de novo biosynthesis of l-serine (l-Ser) via the phosphorylated pathway in human astrocytes. Individuals who are homozygous or compound heterozygous for functionally defective PSP variants exhibit reduced cerebrospinal fluid l-Ser levels and severe neurological symptoms. In the present study, single nucleotide polymorphisms in PSP were identified in hippocampal samples from Alzheimer's disease (AD) patients. Two single nucleotide polymorphisms, likely forming a haplotype (chr7:56088825 T>A and chr7:56088811 T>C, encoding R27S and D32G PSP variants, respectively), were detected exclusively in AD patients (three females and one male). Biochemical characterization of the recombinant R27S/D32G PSP enzyme revealed a slight decrease in thermostability, a 38-fold reduction in catalytic efficiency and a two-fold increase in IC
