Ceftriaxone 1 g versus 2 g per day, for the treatment of community-acquired pneumonia: a retrospective cohort study.
Article in Internal and emergency medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Guidelines recommend intravenous (IV) ceftriaxone at a dose of 1-2 g/d as empirical treatment in adults hospitalized with community acquired pneumonia (CAP), with the addition of macrolide. We examined whether 1 g/d of IV ceftriaxone is associated with similar clinical outcomes to those of 2 g/d. This is a single-center, retrospective, cohort study of all adult patients hospitalized at Rabin Medical Center between 2015 and 2018 with CAP. The primary outcome was 30-day all-cause mortality. Risk factors for 30-day all-cause mortality were identified by univariable and multivariable analyses, using logistic regression analysis. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. A total of 2045 patients were treated with IV ceftriaxone 1 g/d and were and compared to 1944 patients who were treated with 2 g/d. The groups were comparable in their baseline characteristics and their clinical presentation. The 30-day all-cause mortality rate was similar between the groups (301/2045 (14.7%) for 1 g/d vs. 312/1944 (16.0%) for 2 g/d, p = 0.24). The rate of C. difficile infection (CDI) was significantly decreased with 1 g/d compared to 2 g/d (4/2045 (0.2%) vs. 12/1944 (0.6%), p = 0.03) and the length of stay was significantly shorter (median 4 days interquartile range (IQR) 3-7 vs. 5 days IQR 3-8, p = 0.02). None of the blood isolates of Streptococcus pneumoniae were penicillin or ceftriaxone resistant. For hospitalized patients with CAP, IV ceftriaxone 1 g/d was associated with similar mortality rates as IV ceftriaxone 2 g/d, with a decreased rate of CDI and shorter length of stay. Ceftriaxone 1 g/d may be sufficient to treat patients with CAP in countries with low prevalence of drug resistant Streptococcus pneumoniae.
