Antimicrobial treatment for 7 versus 14 days in patients with bacteremia: a meta-analysis of randomized controlled trials.

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
purposeThe optimal duration of antibiotic treatment in patients with bacteremia is a matter of ongoing debate.
methodsWe conducted a meta-analysis of randomized controlled trials that compared 7 days with 14 days of antimicrobial treatment in adults with bacteremia. The systematic search included trials published until December 2024. Efficacy outcomes included 90-day all-cause mortality, recurrence of bacteremia and mean length of hospital stay. Safety outcomes included the total number of adverse events, Clostridioides difficile infections, diarrhea, acute kidney injury, rash or emergence of antibiotic resistance.
resultsThe final analysis included four randomized controlled trials with a total of 4790 participants. Death by day 90 occurred in 321 (13.3%) of 2406 patients receiving antibiotic treatment for 7 days and 342 (14.3%) of 2384 patients receiving antibiotic treatment for 14 days (RR 0.93 [95% CI, 0.81 to 1.07)]; p = 0.30; prediction interval 0.74 to 1.17). The mean hospital stay did not differ significantly (mean difference - 0.18 days [95% CI, -1.03 to 0.67]; p = 0.69; prediction interval - 2.57 to 2.22). Recurrence of bacteremia was similar between antibiotic treatment for 7 days (64 [2.7%] of 2406) and antibiotic treatment for 14 days (56 [2.3%] of 2384) (RR 1.14 [95% CI, 0.80 to 1.63)]; p = 0.47; prediction interval 0.64 to 2.03). Safety outcomes, including the total number of adverse events, Clostridioides difficile infections, diarrhea, acute kidney injury, rash, and antibiotic resistance, were similar between groups.
conclusionsThis meta-analysis suggests that 7-day and 14-day antimicrobial treatment is associated with a similar efficacy and safety profile in patients with bacteremia.
