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
backgroundLow perioperative platelet count is a powerful independent risk factor for posthepatectomy liver failure. Usually, categorical effect of thrombocytopenia was taken into account; upper thresholds were not studied in depth, exclusively in living liver donors.
methodsLiving liver donors who underwent right hepatectomy were included. Preoperative characteristics of donors were identified and examined to predict posthepatectomy liver failure. To eliminate selection bias, one-to-one propensity score matching was performed.
resultsThere were a total of 139 living donors and 40 (29%) donors developed posthepatectomy liver failure in the aftermath of the operation. Remnant liver volume ratio and preoperative platelet count were identified as adjustable independent risk factors (OR: 0.89 and 0.99, 95% CI: 0.79-0.99 and 0.98-0.99, respectively). After propensity score matching, odds ratio of preoperative platelet count was 0.99 (95% CI: 0.98-1.00).
conclusionsPreoperative platelet count, in addition to remnant liver volume ratio, can be used as a surrogate marker to predict the risk of posthepatectomy liver failure in living liver right lobe donors. Probability curves figured out from logistic regression analysis, in this regard, provided an explicit perspective of platelets having a decisive role on liver donor safety. Thus, remaining in safer remnant liver volume ratio limits with respect to preoperative platelet count should be addressed in safe donor selection strategies.
