1 · What the graph read from 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.

2 · The registry

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

objectiveThe objective of this study was to compare graft outcome, operation time and surgical complications of the double and single perichondrium-cartilage underlay techniques for repairing subtotal tympanic membrane (TM) perforations. MATERIALS AND

methodsPatients with unilateral subtotal perforations undergoing myringoplasty were prospectively randomized to undergo DPCN or SPCN. The operation time, graft success rate, audiometric outcomes, and complications were compared between these groups.

resultsIn total, 53 patients with unilateral subtotal perforations were included (DPCN group, 27; SPCN group, 26).All patients completed 6 months of follow-up. The mean operation time was 41.2 ± 1.8 min in the DPCN group and 37.2 ± 5.4 min in the SPCN group, the difference was not significant (p = 0.613).The graft success rates were 96.3% (26/27) in the DPCN group and 73.1% (19/26) in the SPCN group, the difference was significant (p = 0.048). During the period of follow-up, residual perforation was found at postoperative in one (3.7%) in the DPCN group, while cartilage graft slipped (graft lateralization) in 2 (7.7%) and residual perforation in 5 (19.2%) were found in the SPCN group, the difference of residual perforation was not significant among two group (p = 0.177).In addition, no significant between-group differences were observed pre- (p = 0.741) or post- (p = 0.687) operative ABG values or mean ABG gain (p = 0.659) (Table 2).The functional success rates (postoperative ABG ≤ 20 dB) were 85.2% (23/27) in the DPCN group and 73.1% (19/26) in the SPCN group (p = 0.454).

conclusionAlthough similar functional result and operation time can be obtained with double perichondrium-cartilage underlay technique compared to the single perichondrium-cartilage underlay technique for endoscopic closure of subtotal perforations, double unerlay technique offers better anatomical result with minimum complications.
