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
purposeTo assess the normal healing process of limbal-conjunctival autograft (LCA) after pterygium removal during the early postoperative period using anterior segment optical coherence tomography angiography (OCTA).
methodsProspective case series of seven patients undergoing pterygium removal with LCA transplantation procedure, imaged with anterior segment OCTA, and anterior segment colour photos prior to the procedure and on postoperative day (POD) 1, 3, 7 and 30. Revascularization of the graft was analysed quantitatively and qualitatively to estimate patterns of blood vessel growth. Association between revascularization to graft thickness was also investigated.
resultsOn POD 1, all autografts showed either minimal flow signal or no signal at all (Mean 7.1 ± 3.3%). Regrowth of blood vessels into the graft was detected on OCTA scans on POD3 (8.7 ± 3.6%) to 7 (14.3 ± 4.1%), as nonorganised vessels formation in their appearance. Blood vessels were seen growing in a centrifugal pattern towards the surrounding conjunctiva, originating from the underlying episcleral vessels. Revascularization flow signal was seen throughout nearly all graft extent on day 30 (21.6 ± 2.2%). Graft oedema was evident on the first week (Mean 611 ± 120 μm, 695 ± 84 μm, 639 ± 96 μm of POD 1, 3 and 7, respectively), reducing substantially by day 30 (300 ± 108 μm).
conclusionsOCTA imaging can be used to assess the LCA healing process during the early postoperative period. Revascularization occurring as early as 3-7 days post-surgery, seems to originate from the underlying episcleral vessels. Therefore, careful handling of the bare scleral surface during surgery may be prudent for achieving an adequate healing process.
