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

Injectable antimicrobials with documented prolonged dosing intervals (> 48 h) for use in rhesus macaques are sparse. The objective of our study was to assess the pharmacokinetics, urine excretion, and effects on gut microbiome and resistome of intramuscular administered long-acting formulation of ampicillin (Albipen LA) in macaques. Four female rhesus macaques (Macaca mulatta) were administered intramuscularly 25 mg/kg anhydrous ampicillin (AMP-LA). Serial plasma samples were collected over a 72 h period and urine samples were collected over a 150 h period. Rectal swabs were collected over a 180-day period for microbiome and resistome analysis. Both plasma and urine samples were analyzed with ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The pharmacokinetic parameters for AMP-LA ranged as follows: C
