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

objectiveThe present study aimed to establish a user-friendly practical way to prepare phantoms for routine quantitative

methodsWe produced gallium ions in 0.05 M HCl from a

resultsThe visible distribution of activity in the phantom prepared using method (ii) was not uniform with peripheral accumulation, and spatial uniformity progressively deteriorated over time. The SD increased from 0.0206 to 0.0361 at 5 and 60 min, respectively. In contrast, the phantoms prepared using the other four methods yielded visually homogeneous images and the methods (iii), (iv), and (v) maintained relatively stable SDs throughout image acquisition. The CV increased modestly over time under all conditions, and was consistent with decreasing count statistics, whereas SUV
