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
Introduction: Midline catheters are a promising alternative to central venous access devices for intermediate-term therapy, with reduced risks of catheter-related bloodstream infections (CRBSI) and deep vein thrombosis (DVT). Their inclusion in the 2024 World Health Organization guidelines reflects increasing global interest. However, their use remains limited to select countries, and real-world clinical data are scarce. This study evaluated the safety and effectiveness of midline catheters in an acute care setting. Methods: We retrospectively analyzed 68 midline catheter insertions in 50 patients between November 2023 and April 2024 in a general internal medicine ward of a 400-bed hospital. Collected data included patient demographics, indications for use, catheter dwell time, number of blood draws, and occurrence of complications. Insertions were ultrasound-guided and performed under sterile precautions. Weekly site disinfection and dressing changes were implemented. Complications were classified as major (CRBSI, symptomatic DVT) or minor (occlusion, poor return, leakage, unintentional removal). Results: Median age was 59.5 years (IQR 70-85.75); 46 % were female. All patients required frequent blood sampling. Common indications included prolonged antibiotic therapy (72 %) and difficult venous access (38 %). Median dwell time was 11 days, with a median of 4 blood draws. No CRBSI or symptomatic DVT occurred. Minor complications included leakage (n = 7), unintentional removal (n = 8), poor return (n = 4), and occlusion (n = 1). Conclusion: Midline catheters demonstrated a favorable safety profile, with no major complications and minor complication rates comparable to international data. Preventive strategies should target vulnerable patients to reduce unintentional catheter removal.
