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

backgroundThe mostly used threshold-based segmentation method for SPECT, i.e., 42% of the maximum intensity, was derived from PURPOSE: This study aims to revisit the optimal segmentation threshold for

methodsA cylindrical Jaszczak phantom containing six spheres (2-113 mL) was imaged via simulation and physical experiments using a clinical dual-head NaI SPECT/CT system. The spheres were filled with

resultsThe optimal threshold increased along with the decrease in sphere volume or SBR. For SBR ≥ 3.5:1 and volume ≥ 16 mL, the mean optimal threshold of

conclusionsAn optimal
