Weight changes in heart failure with preserved ejection fraction: findings from TOPCAT.
Trial report in Clinical research in cardiology : official journal of the German Cardiac Society, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundWeight loss has been associated with poor outcomes in patients with heart failure (HF). However, few data are available for patients with heart failure with preserved ejection fraction (HFpEF). The impact of weight gain on outcomes has not been frequently reported either.
aimsTo study post-randomization weight changes and how these could impact outcomes and the effect of spironolactone in patients with HFpEF enrolled in the TOPCAT-Americas trial (N = 1767).
methodsMixed-effects regressions and time-updated Cox models to assess the factors associated with weight changes and their impact on subsequent outcomes.
resultsOver a median follow-up of 3 years, 824 (47%) patients experienced weight loss ≥ 5% and 390 (22%) experienced weight loss ≥ 10%. Patients experiencing weight loss were older and more frequently women with severe HF symptoms. Spironolactone slightly reduced body weight before 12 months of follow-up: β = - 0.55 (- 0.82 to - 0.29) kg, without effect on weight afterwards: β = 0.01 (- 0.66 to 0.68) kg; treatment-by-time interaction P = 0.0015. Spironolactone did not increase the odds of weight loss but reduced the odds of weight gain. Weight loss ≥ 5% was associated with a higher risk of cardiovascular and all-cause death irrespective of baseline body mass index: HR = 1.47, 95%CI = 1.07-2.01 and HR = 1.84, 95%CI = 1.46-2.31, respectively. Weight gain was not associated with an increased risk of any outcome.
conclusionWeight loss ≥ 5% was frequent and independently associated with an increased risk of subsequent mortality. Spironolactone induced only slight body weight reductions early after its introduction and up to a maximum of 8-12 months of follow-up. Association between body weight changes and subsequent death.

Model adjusted on age, sex, race, NYHA class, systolic blood pressure, diabetes, atrial fibrillation, previous myocardial infarction, previous heart failure hospitalization, estimated glomerular filtration rate, diuretic use, and baseline weight.
