Comparison between OK-432 and Talc for pleurodesis in patients with persistent pulmonary air leak: a Japanese nationwide retrospective database study.
Article in General thoracic and cardiovascular surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesOK-432 (Picibanil
methodsThis retrospective study used data from the Japanese Diagnosis Procedure Combination inpatient database. Patients with pneumothorax who underwent chemical pleurodesis between July 2010 and March 2022 were included in this study. The patients were categorized into two groups: the OK-432 and talc groups. The primary outcome measure was treatment failure, defined as a composite of requirement for additional surgical procedures, bronchoscopic interventions, or chemical pleurodesis. The secondary outcome measures were in-hospital mortality, length of hospital stay, 30-day readmission, and incidence of interstitial lung diseases after hospitalization. To compare the outcomes between the groups, 1:4 propensity score matching was conducted.
resultsAmong the 4179 eligible patients, 3551 and 628 patients underwent chemical pleurodesis using OK-432 and talc, respectively. Propensity score matching yielded 2508 and 627 patients who underwent chemical pleurodesis using OK-432 and talc within seven days of admission, respectively. The frequency of treatment failure in the talc group (37.5% vs. 31.4%; P = 0.006) was lower than that in the OK-432 group with no significant differences in other outcomes.
conclusionsMedical professionals can consider talc as the initial pleurodesis agent for patients with persistent air leaks.
