Heart failure in ALLHAT: did blood pressure medication at study entry influence outcome?
Trial report in Journal of clinical hypertension (Greenwich, Conn.), 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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
J Clin Hypertens (Greenwich). 2009;11:466-474. (c)2009 Wiley Periodicals, Inc.Lower heart failure (HF) rates in individuals taking chlorthalidone vs amlodipine, lisinopril, or doxazosin were unanticipated in the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT). HF differences appeared early, leading to questions about the possible influence of pre-enrollment antihypertensive drugs. A post hoc study evaluated hospitalized HF events. During year 1479 individuals had HF, with pre-entry antihypertensive medication data obtained on 301 patients (63%). Case-only analysis examined interactive effects (interaction odds ratio [OR, ratio of ORs]) of previous medication and ALLHAT treatment on HF outcomes, eg, did treatment effect differ by pre-entry antihypertensive class? Among cases, 39%, 37%, 17%, and 47% were taking pre-entry diuretics, angiotensin-converting enzyme inhibitors, beta-blockers, and calcium channel blockers, respectively. Interaction OR for year 1 HF for amlodipine vs chlorthalidone for patients taking vs not taking diuretics pre-entry was 1.08 (95% confidence interval [CI], 0.53-2.21; P=.83); for lisinopril vs chlorthalidone, 1.33 (95% CI, 0.65-2.74; P=.44); and for doxazosin vs chlorthalidone, 1.13 (95% CI, 0.57-2.25; P=.73). Controlling for other pre-entry antihypertensives yielded similar results. There was no significant evidence that pre-entry drug type explained observed hospitalized HF differences by ALLHAT treatment.
