Use of doripenem and risk of seizure and renal impairment in US hospitalized patients: a retrospective cohort study.
Article in Therapeutic advances in drug safety, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesA large retrospective database study was conducted to assess the incidence rate of treatment-emergent renal impairment/failure, seizure, and hemolytic anemia in doripenem and imipenem intravenous (IV)-exposed patients treated for complicated urinary tract infection (cUTI) and complicated intra-abdominal infection (cIAI) in US hospitals.
methodsUsing the Premier Perspective™ Database (PPD), which maintains hospital discharge records for over 309 million patients, the incidence rate of treatment-emergent renal impairment/failure, seizure, and hemolytic anemia in the doripenem-treated compared with imipenem IV-treated population was examined.
resultsThe unadjusted doripenem rate ratio (RR) for renal impairment/failure relative to imipenem IV was 1.13 [95% confidence interval (CI) 1.07-1.21; p < 0.0001]. The unadjusted doripenem rate ratio for seizure relative to imipenem IV was 0.74 (95% CI 0.52-1.05; p = 0.07). In the comparative safety analysis, adjusted incidence rates of renal impairment/failure between doripenem-exposed patients and a propensity score-matched comparator cohort of imipenem IV-exposed patients showed no statistically significant difference in cUTI [RR = 1.02; 95% CI 0.93-1.12; p = 0.71] or cIAI (RR = 1.17; 95% CI 1.00-1.36; p = 0.05). Likewise, there was no statistically significant difference in adjusted incidence rates for seizures in doripenem-treated versus matched imipenem-treated patients for cUTI (RR = 0.69; 95% CI 0.41-1.14; p = 0.15) or cIAI (RR = 0.45; 95% CI 0.15-1.41; p = 0.17). No hemolytic anemia events were observed in this study.
conclusionsIn this large retrospective cohort study of US hospitalized patients, no statistically significant differences in the adjusted relative rates of renal impairment/failure and seizure were observed between doripenem and a propensity score-matched comparator cohort of imipenem IV patients in the treatment of cUTI and cIAI.
