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
backgroundChronic rhinosinusitis (CRS) is a syndrome with multifactorial aetiology. Amongst which, anatomical variations studied by computed tomography of paranasal sinuses (CT PNS) had a high incidence which varied between 64.0% and 99.8%
methodA prospective observational study was conducted in 70 CRS patients and were subjected to CT PNS. CT PNS is studied to know the various anatomical variations & other CT findings causing CRS and then findings noted down, tabulated and statistical analysis done.
resultsAll 70 CRS patients evaluated by CT PNS had one or more anatomical variations along with other findings like fungal sinusitis in 6 patients, dentigerous cyst and inverted papilloma in 1 case each. The anatomical variations observed in our study were septal deviation(62.8%), concha bullosa(52.8%), agger nasi(51.4%), pneumatized crista galli(47.1%), hyperpneumatized bulla(40%), suprabullar cells(37%), septal spur(34.3%), paradoxically curved middle turbinate(34.2%), supra orbital cells(32.8%), haller cells(31.4%), septal pneumatization(17.1%), pneumatized uncinate(13%), interfrontal septal pneumatization(13%), maxillary septations(10%), maxillary sinus hypoplasia(7.1%), frontal hypoplasia(5.7%), uncinate attached to lamina papyracea(40%), uncinate to middle turbinate(11%), uncinate to skull base(7.9%), free uncinate(41%), frontal cells type 1;2;3;4 (36%);(30%);(20%);(38.5%), onodi cells(27.1%), pneumatized anterior clinoid process(18.5%), lateral recess(15.7%), sphenoid septations attached to optic nerve(10%) and carotid(2.8%), pneumatized superior turbinate(1.4%), Sellar; Pre sellar; Post sellar sphenoid(42.8%);(5.7%);(51.4%). In our study only anatomical variations around the maxillary & Frontal sinus showed significant association with CRS.
conclusionAnatomical variations around the anterior group of sinuses have a significant association with CRS.
