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
backgroundIncreased B-type natriuretic peptide (BNP) and decreased free triiodothyronine (fT3) are associated with increased mortality after cardiac surgery. However, previous studies have addressed mortality primarily in patients undergoing coronary artery bypass graft, and not in those undergoing valve surgery. We assessed abilities of BNP and fT3 to predict mortality after valve surgery.
methodsThis retrospective study included 1050 consecutive patients who underwent valve surgery with normothermic cardiopulmonary bypass (CPB). Predictors of in-hospital mortality were identified with logistic regression analyses. Cutoff values were determined with receiver operating curve analyses.
resultsThere were 23 deaths (2.2%). By univariate analyses, fT3, log-transformed BNP (log BNP), cholinesterase, estimated glomerular filtration rate, and albumin were profoundly associated with in-hospital mortality (p < 0.0001 for each). By a multivariate analysis, however, only fT3 and log BNP remained significant (p = 0.0053 and p = 0.0449, respectively). fT3 and log BNP remained significant after adjustment for CPB time, and also after adjustment for the EuroSCORE II or JapanSCORE (p < 0.05 for each). Odds ratio and 95% confidence interval from univariate binary analysis for in-hospital mortality were 7.22 (3.12-17.58) for fT3 ≤ 2.21 pg/mL, 6.01 (2.54-15.77) for BNP ≥ 219 pg/mL, and 9.79 (4.21-22.74) for both combined (p < 0.0001 for each).
conclusionsfT3 and BNP predict in-hospital mortality after valve surgery, independent of each other, independent of CPB time, and independent of established mortality risk SCOREs. Additions of fT3 and BNP may enhance predictive utilities of established mortality risk SCOREs.
