Trastuzumab Induces an Immediate, Transient Volume Increase in Humans: A Randomised Placebo-Controlled Trial.
Trial report in EBioMedicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 exact extent of and the mechanism by which trastuzumab causes cardiac side effects are not completely unravelled. We investigated the (cardiotoxic) side effects of trastuzumab in a relatively large homogeneous population.
methodsHealthy male volunteers (n = 54) with a left ventricle ejection fraction (LVEF) > 55% were administered 6 mg/kg trastuzumab (n = 46) IV in 90 min in a placebo-controlled, parallel study. Placebo consisted of 0 · 9% NaCl (n = 8). Assessments included body weight, routine and cardiac laboratory markers and serial echocardiographic examinations (8 placebo and 9 trastuzumab treated participants) up to 63 days after dosing. Statistical analysis was done using repeated measurements of variance.
findingsFollowing trastuzumab infusion, fluid retention was observed: mean body weight increased over the first 4 days post-administration with 0 · 4 kg (95%-confidence interval: - 0 · 2, 0 · 9, p = 0 · 2261) compared to placebo, mean haemoglobin concentration decreased with 0 · 3 mM (- 0 · 6, - 0 · 1; p = 0 · 0043), as did haematocrit (- 0 · 013 L/L [- 0 · 024, - 0 · 002], p = 0 · 0216), and protein (- 2 g/L [- 4, - 0], p = 0 · 0443) and albumin (- 2 g/L [- 3, - 1], p < 0 · 0001) concentrations. Elevations in NT-proBNP levels, parallel to the weight increase, were observed in individual cases, but not on a group level. Troponin-T concentrations did not increase. The only echocardiographic parameter that changed significantly at all studied dose levels was E/A-ratio, a load-dependent parameter: from 1 · 81 (SD 0 · 42) to 1 · 98 (0 · 31) 3-5 days after administration, contrast to placebo of 0 · 57 (90%-CI: 0 · 21-0 · 93, p = 0 · 0034). Ejection fraction and pulsed-wave Doppler recorded parameters remained unchanged.
interpretationSingle dose administration of trastuzumab in humans is associated with an immediate, transient extracellular volume increase, either as a primary or secondary (compensatory) response, which can be detected easily using routine clinical assessments. Echocardiographic changes, both short and long term, could not be found after single dose administration to drug-naive patients.
