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
Background: Persistent air leak (PAL) is a frequent and challenging complication of secondary spontaneous pneumothorax (SSP) and often prolongs hospitalization. We compared the efficacy and safety of autologous blood patch pleurodesis (ABPP) plus doxycycline with those of ABPP alone for managing PAL in patients with SSP who were considered unfit for surgery. Methods: This prospective, randomized controlled trial enrolled 121 patients with SSP and PAL lasting ≥7 days. Participants were randomized to receive ABPP alone (n=62) or ABPP plus intrapleural doxycycline (n=59). The primary outcome was time to air leak cessation. Secondary outcomes included the 7-day success rate, time to drain removal, length of hospital stay, pain score, complications, and recurrence at 1 and 3 months. Results: Kaplan-Meier analysis showed significantly faster air leak cessation in the ABPP plus doxycycline group than in the ABPP-alone group (median, 4 days vs. 6 days; log-rank p<0.001). This was accompanied by earlier intercostal drain removal (median, 5 days vs. 7 days; p<0.001) and a shorter hospital stay (median, 12 days vs. 14 days; p<0.001). The 7-day success rate was 81% in the combination group and 74% in the ABPP group (p=0.34). Post-procedural pain scores were higher in the combination group (p<0.001). However, overall complication rates (36% vs. 40%, p=0.6) and 3-month recurrence rates (3.8% vs. 7%, p=0.68) were statistically comparable between groups. Conclusion: Combining doxycycline with ABPP appears to be a safe and effective bedside intervention. Compared with ABPP alone, the combination significantly accelerated air leak cessation and shortened hospitalization, while achieving pleural symphysis without increasing major complications (trial registration number: Pan African Clinical Trials Registry, PACTR202505753650802).
