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

CA1 is a subfield in the human hippocampus that is particularly vulnerable to hypoxia. Previous stereological studies on CA1 have examined primarily male samples, leaving female total neuron counts not represented or underrepresented in total neuron count and neuron size studies. Our study sought to fill in the gap and provide baseline data on an equal number of male and female brains, representing both hemispheres with optimal stereology methods. Twenty-two human brain hemispheres, 11 females, 11 males (9 right hemispheres, 13 left hemispheres), were counted using the optical fractionator and nucleator probes for total neuron count and mean neuron volumes. Hippocampal volume was measured in a subset of 20 samples from 1 mm isotropic ex vivo MRI. The CA1 total neuron count across all samples was 5.01 × 10
