Liver cyst penetration of antibiotics at the target site of infection: a randomized pharmacokinetic trial.
Trial report in The Journal of antimicrobial chemotherapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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 EASL cystic liver disease guideline states that drug penetration at the site of infection (liver cyst) is essential for successful treatment, but pharmacokinetic (PK) data on cyst penetration are limited.
objectivesThis study aims to investigate tissue penetration of four antibiotics in non-infected liver cysts and explores influencing factors.
methodsWe performed a prospective, randomized single-dose PK-study. Before percutaneous drainage of a non-infected liver cyst, an intravenous (IV) dose of either ciprofloxacin and piperacillin/tazobactam (group 1); or co-trimoxazole (trimethoprim/sulfamethoxazole) and doxycycline (group 2) was given. Cyst fluid was collected during drainage. Blood samples were obtained before, during and after drainage (within 12 h). Drug concentrations were measured with a validated LC-MS/MS. Primary outcome was liver cyst penetration, defined as the cyst-fluid-to-plasma concentration ratio (%) expressed as median (IQR).
resultsWe included 20 patients, and 21 liver cysts were drained (group 1: n = 11, group 2: n = 10). Median drained cyst volume was 700 mL. Median time between infusion and drainage was 139 min (IQR 120-188 min). Median cyst-fluid-to-plasma concentration ratio was 4.2% (IQR 1.6%-8.9%) for ciprofloxacin, 0.3% (IQR 0.0%-1.3%) for piperacillin, 0.2% (IQR 0.0%-1.3%) for tazobactam, 12.2% (IQR 6.3%-16.1%) for trimethoprim, 0.4% (IQR 0.2%-3.8%) for sulfamethoxazole and 1.6% (IQR 0.9%-2.3%) for doxycycline. Time between trimethoprim infusion and cyst drainage was correlated with increased cyst-fluid-to-plasma concentration ratio (P < 0.01).
conclusionsTrimethoprim and ciprofloxacin have the highest penetration ratios amongst antibiotics tested. We found that liver cyst penetration varies widely between drugs after a single IV dose. CLINICAL TRIAL NUMBER: NTR8499The trial was originally registered in the Netherlands Trial Register (ID: NL7290), which was converted to the International Clinical Trials Registry Platform in 2022.
