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: Drug-resistant tuberculosis (DR-TB) is the most exigent and calamitous challenge encountered in treatment of TB. Extra pulmonary (EP) DR-TB poses a complex diagnostic and therapeutic challenge owing to myriad of presentations and paucibacillary nature. Data available on this subset is limited. We studied the prevalence of EPDR-TB cases among the total DR-TB cases visiting our Programmatic management of Drug-Resistant TB (PMDT) site. We also studied the demographic and microbiological profile of these cases and analyzed the prevalence of pre-extensively drug-resistant TB (pre XDR-TB) and extensively drug-resistant TB (XDR-TB) among patients of EPDR-TB in pre Bdq era. Results: Of the 1086 DR-TB patients, 64 (5.89%) were cases of EPDR-TB. Seven out of 64 (10.93%) were primary EPDR-TB. The site wise distribution of cases was 34 (53.125%) lymph node DR-TB, 18 (28.125%) pleural DR-TB, 9 (14.0625%) spinal DR-TB/paraspinal abscess/psoas abscess, 1 case (1.5625%) each of abdominal DR-TB, sternal and gluteal abscess. On the basis of the second-line drug susceptibility testing (DST), patients were grouped into: (1) multidrug-resistant TB (MDR-TB), (2) MDR-TB with fluoroquinolone (FQ) resistance {pre XDR XDR-TB (FQ)}, (3) MDR-TB with second-line injectable (SLI) resistance {pre XDR XDR-TB (SLI)}, (4) XDR-TB. Of the 64 patients, 43 (67.185%) had MDR-TB, 19 (29.687%) had preXDR-TB (FQ), none had preXDR-TB (SLI) and 2 (3.125%) had XDR-TB. Gastro esophageal reflux disease (GERD) was the most common comorbidity seen in 26 (40.6%) patients, followed by anemia in 5 (7.8%), psychiatry problems 5 (7.8%), hypertension in 3 (4.6%), renal disorders in 2 (3.1%) while thyroid disorder, HIV and thalassemia in 1 each (1.5%). Conclusion: EPDR-TB forms a small but significant proportion of total DR-TB. Lymph node DR-TB is its most common subclass. Our study emphasises the momentousness and essentiality of baseline DST to FQ and SLI in patients of DR-TB. This enables an appropriate modification of therapy at baseline itself to better the treatment outcomes. We observed a strikingly high proportion of preXDR-TB (FQ) in our study group.
